Can't modify user admin and other suphp problem.

[Richard G]

I want to modify user admin, he has everything enabled:

I want to set these 4 to off:
Shell Access (ssh) ON
Shell for Resellers's Users ON
Secure Socket Layer (ssl) ON
Anonymous Ftp ON

But if I do that via DA control panel and modify user admin, and click save, the changes are not saved.
PHP 5.3.9 (cli) (suphp)
Centos 5.6

What's going wrong here?

Same goes for Castcontrol. I uploaded all files to the server. I visit the page, but I don't get an installation page, only a error 500 in my browser.
All php files are ad user:user every file/directory has 755 or 644, so no 777 or something like that.

But I still get the error 500. The suphp.log keeps 0 bytes without any lines mentioning something about the error 500.
Also httpd access and error logs are not telling me anything.

What is going wrong here?

The suphp part is solved. Ioncube loader had to be loaded, but this error was not displayed to me.

Still wondering why I cant adjust those admin settings.
