I am using cpg one year without problems , but now I cannot upload images. After uploading system response "uploads were successful." but i don't see anything.
debug mode show me this
Notice: Undefined index: OS in /DISK3/WWW/orechdaczech.com/www/include/picmgmt.inc.php on line 157
Warning: shell_exec() has been disabled for security reasons in /DISK3/WWW/orechdaczech.com/www/include/picmgmt.inc.php on line 171
please help
The error message means that your webhost has changed his security policy, so you can't use ImageMagick anymore. Go to coppermine's config, set "method for resizing images" to "GD2" and try if this works for you. If it doesn't, contact your webhost.

P.S. Disable notices_display in debug_mode, unless you are a developer and know your way around.
