Hi Abhiram,

All OJS 2.x releases need to be able to create and manage directories; with Safe Mode's UID restriction, this isn't possible. OJS is able to create directories, but as they are created with the web server's UID, it is not then able to access them. PHP's "safe mode" feature in this situation is badly broken and you'll need to work with your ISP to work around it. If they can provide details on a method for creating directories with the correct UID, I'd be happy to suggest suitable changes for OJS to make use of it.

Hi,
Our ISP disabled that safemode option temporarily and then enable shell_exec() , so i could upload that file. They told me its not a permanent option to disable that safemode option. After some time , when i try to upload a file some error occurs.

Hi Abhiram,

Temporarily disabling the safe mode restriction is not a solution, as OJS needs to be able to create a directory for each submission. In any case, the reason that you're seeing these error messages is that the directories created by previous uploads can not be written to by OJS and will need to be changed with "chmod" and/or "chown" commands (ideally by connecting to the server using SSH or FTP).

PHP's safe mode UID restriction is generally considered to be badly broken, and you'll need to work with your ISP to determine an ongoing way of allowing OJS to create directories that it can then administer.

If your ISP is willing to relax the UID restriction into a GID (group ID) restriction, you may be able to configure permissions so that OJS works in this situation.
