I'm posting this here in the hopes that someone can help...
In April the server was hacked and index.php was replaced, I'm not sure if that may have
effected it?
Anyway. http://arena.kailyn.co.uk. Using net pbm for the
thumbnails, but when an image is uploaded this error appears at the top of the screen:
Warning: system() has been disabled for security reasons in
/home/kailyn/public_html/arena/includes/image_utils.php on line 111
In the control panel there's an option to check the database for missing thumbnails and replace
them, when you try and run that you get this error:
Create thumbnail for: RKO King Nanook of the Tundera, pkc# A1579,male, Alaskan Malamute (Nanook.jpg)
....
Warning: system() has been disabled for security reasons in
/home/kailyn/public_html/arena/includes/image_utils.php on line 111
Error creating thumbnail!
Any ideas what could be causing this and what we can do to fix it?
Thanks, I have pasted image_utils.php below.
