I'm using NG Version 1.9.3.
I have a slightly different problem from what I can see from the forum posts. I am getting HTTP errors when I attempt to upload files but the error log doesn't mention mod_security.
The errors are along the type of:
[10-Jun-2012 22:45:24] PHP Warning: reset() [<a href='function.reset'>function.reset</a>]: Passed variable is not an array or object in /home2/XXXXXXXXXXXXXXX/wp-content/plugins/nextgen-gallery/nggfunctions.php on line 704
But you can see the full error log at http://templatesagogo.com/root-error-log/error_log.txt
Any help on this?
