    The Zend Engine API version 220060519 which is installed, is outdated.

    I had upgrade php to 5.4 from 5.2.7 and all sites had lots of errors. So I revert back to 5.2.7 and all are fine now. But I see this in logs :

    Zend Guard Loader requires Zend Engine API version 220090626.
    The Zend Engine API version 220060519 which is installed, is outdated.

    How can I fix this?

    cd /usr/local/directadmin/custombuild
    ./build zend
    This should fix.

    I tried that already :

    [root@lxn1 custombuild]# cd /usr/local/directadmin/custombuild
    [root@lxn1 custombuild]# ./build zend
    File already exists: ZendOptimizer-3.3.3-linux-glibc23-i386.tar.gz

    You should remove Zend Guard Loader lines from php.ini file.

    Thank you guys. But not sure what lines to remove. I see: (sorry for long post)

    zend_extension = /usr/local/ioncube/
    and also this:
    and these:
    # Add the following:# Add the following:
    zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.sozend_extension = 
    /usr/local/ioncube/;;;;;;;;;;;;;;;;;;; ; About php.ini ; ;;;;;;;;;;;;;;;;;;; ; This file controls many 
    aspects of PHP's behavior.  In order for PHP to ; read it, it must be named 'php.ini'.  PHP looks for it in the current ; working 
    directory, in the path designated by the environment variable ; PHPRC, and in the path that was defined in compile time (in that 
    order). ; Under Windows, the compile-time path is the Windows directory.  The ; path in which the php.ini file is looked for can be 
    overridden using ; the -c argument in command line mode. ; ; The syntax of the file is extremely simple.  Whitespace and Lines ; 
    beginning with a semicolon are silently ignored (as you probably guessed). ; Section headers (e.g. [Foo]) are also silently 
    ignored, even though ; they might mean something in the future. ; ; Directives are specified using the following syntax: ; 
    directive = value ; Directive names are *case sensitive* - foo=bar is different from FOO=bar. ; ; The value can be a string, a 
    number, a PHP constant (e.g. E_ALL or M_PI), one ; of the INI constants (On, Off, True, False, Yes, No and None) or an expression ; 
    (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo"). ; ; Expressions in the INI file are limited to bitwise operators and 
    parentheses: ; | bitwise OR ; & bitwise AND ; ~ bitwise NOT ; !  boolean NOT ; ; Boolean flags can be turned on using the values 1, 
    On, True or Yes. ; They can be turned off using the values 0, Off, False or No. ; ; An empty string can be denoted by simply not 
    writing anything after the equal ; sign, or by using the None keyword: ; ; foo = ; sets foo to an empty string ; foo = none ; sets 
    foo to an empty string ; foo = "none" ; sets foo to the string 'none' ; ; If you use constants in your value, and these constants 
    belong to a ; dynamically loaded extension (either a PHP extension or a Zend extension), ; you may only use these constants *after* 
    the line that loads the extension. ; ; ;;;;;;;;;;;;;;;;;;; ; About this file ; ;;;;;;;;;;;;;;;;;;; ; This is the recommended, PHP 
    5-style version of the php.ini-dist file.  It ; sets some non standard settings, that make PHP more efficient, more secure, ; and 
    encourage cleaner coding. ; ; The price is that with these settings, PHP may be incompatible with some ; applications, and 
    sometimes, more difficult to develop with.  Using this ; file is warmly recommended for production sites.  As all of the changes 
    from ; the standard settings are thoroughly documented, you can go over each one, ; and decide whether you want to use it or not. ; 
    ; For general information about the php.ini file, please consult the php.ini-dist ; file, included in your PHP distribution. ; ; 
    This file is different from the php.ini-dist file in the fact that it features ; different values for several directives, in order 
    to improve performance, while ; possibly breaking compatibility with the standard out-of-the-box behavior of ; PHP.  Please make 
    sure you read what's different, and modify your scripts ; accordingly, if you decide to use this file instead. ; ; - 
    register_long_arrays = Off [Performance] ; Disables registration of the older (and deprecated) long predefined array ; variables 
    ($HTTP_*_VARS).  Instead, use the superglobals that were ; introduced in PHP 4.1.0 ; - display_errors = Off [Security] ; With this 
    directive set to off, errors that occur during the execution of ; scripts will no longer be displayed as a part of the script 
    output, and thus, ; will no longer be exposed to remote users.  With some errors, the error message ; content may expose 
    information about your script, web server, or database ; server that may be exploitable for hacking.  Production sites should have 
    this ; directive set to off. ; - log_errors = On [Security] ; This directive complements the above one.  Any errors that occur 
    during the ; execution of your script will be logged (typically, to your server's error log, ; but can be configured in several 
    ways).  Along with setting display_errors to off, ; this setup gives you the ability to fully understand what may have gone wrong, 
    ; without exposing any sensitive information to remote users. ; - output_buffering = 4096 [Performance] ; Set a 4KB output buffer.  
    Enabling output buffering typically results in less ; writes, and sometimes less packets sent on the wire, which can often lead to 
    ; better performance.  The gain this directive actually yields greatly depends ; on which Web server you're working with, and what 
    kind of scripts you're using. ; - register_argc_argv = Off [Performance] ; Disables registration of the somewhat redundant $argv 
    and $argc global ; variables. ; - magic_quotes_gpc = Off [Performance] ; Input data is no longer escaped with slashes so that it 
    can be sent into ; SQL databases without further manipulation.  Instead, you should use the ; database vendor specific escape 
    string function on each input element you ; wish to send to a database. ; - variables_order = "GPCS" [Performance] ; The 
    environment variables are not hashed into the $_ENV.  To access ; environment variables, you can use getenv() instead. ; - 
    error_reporting = E_ALL [Code Cleanliness, Security(?)] ; By default, PHP suppresses errors of type E_NOTICE.  These error messages 
    ; are emitted for non-critical errors, but that could be a symptom of a bigger ; problem.  Most notably, this will cause error 
    messages about the use ; of uninitialized variables to be displayed. ; - allow_call_time_pass_reference = Off [Code cleanliness] ; 
    It's not possible to decide to force a variable to be passed by reference ; when calling a function.  The PHP 4 style to do this is 
    by making the ; function require the relevant argument by reference. ; - short_open_tag = Off [Portability] ; Using short tags is 
    discouraged when developing code meant for redistribution ; since short tags may not be supported on the target server.

    Remove all of the zend_extension* and zend_optimizer* lines.
    Once it's all cleared out, then re-install them.

    If unsure, install a fresh php.ini.
    A fresh copy can be found in the php-x.x.x.tar.gz file as php.ini-dist or php.ini-production, etc..

    Or.. just delete all of your php.ini files and recompile php.
    This will add any php.ini files if they're missing.

    Once a fresh php.ini is present, then re-install zend and/or ioncube as needed.

    I have:

    Zend OPcache requires Zend Engine API version 220121212.
    The Zend Engine API version 220131226 which is installed, is newer.

    And in /usr/local/lib/php.ini no Zend Guard Loader lines but :

    ; Enables or disables the circular reference collector.
    zend.enable_gc = On
    ; Determines if Zend OPCache is enabled
    ; Determines if Zend OPCache is enabled for the CLI version of PHP
    ;era opcache.enable_cli=1 modificato da PP il 13-04-2015
    ; The OPcache shared memory storage size.
    ; The amount of memory for interned strings in Mbytes.
    ; The maximum number of keys (scripts) in the OPcache hash table.
    ; Only numbers between 200 and 100000 are allowed.
    ; The maximum percentage of "wasted" memory until a restart is scheduled.
    ; When this directive is enabled, the OPcache appends the current working
    ; directory to the script key, thus eliminating possible collisions between
    ; files with the same name (basename). Disabling the directive improves
    ; performance, but may break existing applications.
    ; When disabled, you must reset the OPcache manually or restart the
    ; webserver for changes to the filesystem to take effect.
    ; How often (in seconds) to check file timestamps for changes to the shared
    ; memory storage allocation. ("1" means validate once per second, but only
    ; once per request. "0" means always validate)
    ; Enables or disables file search in include_path optimization
    ; If disabled, all PHPDoc comments are dropped from the code to reduce the
     ;size of the optimized code.
    ; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
    ; may be always stored (save_comments=1), but not loaded by applications
    ; that don't need them anyway.
    ; If enabled, a fast shutdown sequence is used for the accelerated code
    ; Allow file existence override (file_exists, etc.) performance feature.
    ; A bitmask, where each bit enables or disables the appropriate OPcache
    ; passes
    ; The location of the OPcache blacklist file (wildcards allowed).
    ; Each OPcache blacklist file is a text file that holds the names of files
    ; that should not be accelerated. The file format is to add each filename
    ; to a new line. The filename may be a full path or just a file prefix
    ; (i.e., /var/www/x  blacklists all the files and directories in /var/www
    ; that start with 'x'). Line starting with a ; are ignored (comments).
    ; Allows exclusion of large files from being cached. By default all files
    ; are cached.
    ; Check the cache checksum each N requests.
    ; The default value of "0" means that the checks are disabled.
    ; How long to wait (in seconds) for a scheduled restart to begin if the cache
    ; is not being accessed.
    ; OPcache error_log file name. Empty string assumes "stderr".
    ; All OPcache errors go to the Web server log.
    ; By default, only fatal errors (level 0) or errors (level 1) are logged.
    ; You can also enable warnings (level 2), info messages (level 3) or
    ; debug messages (level 4).
    ; Preferred Shared Memory back-end. Leave empty and let the system decide.
    ; Protect the shared memory from unexpected writing during script execution.
    ; Useful for internal debugging only.
