One of our users has a chmod command in a php script and it kicks out the following errors..


Warning: chmod(): Operation not permitted in
/home/jcurtis/domains/curtis-associates.co.uk/public_html/surveys/medieval/p
rocess.php on line 92

Warning: chmod(): Operation not permitted in
/home/jcurtis/domains/curtis-associates.co.uk/public_html/surveys/medieval/p
rocess.php on line 109

Warning: Cannot modify header information - headers already sent by (output

rocess.php on line 121

Anyone got any ideas?

Cheers,

What file/directory is the script trying to chmod? My first guess would be that the user running the script (apache) doesn't have privileges to chmod the file/directory (probably owned by the user).

Click to expand...

It's a text file, the script (all looks ok) chmods it to 755, writes and then chmods it back to 600

We've seen similar problems with Mambo, which we resolved by running a cronjob to automatically chmod the proper directories from time to time.

Hello,

You could put an @ (error suppression flag) infront of each of the CHMOD commands on lines 92 and 109 of /home/jcurtis/domains/curtis-associates.co.uk/public_html/surveys/medieval/process.php.

At least that will get rid of the error and allow PHP to sucessfully modify the headers it wants to change. :)

Good luck!
 
safe_mode on and/or chmod() or related functions being disabled in the php.ini might cause this problem.
 
Do you mean that if safe_mode is set as on server wide and then disabled for the individual user it would keep the chmod from working?

:(
