First of all: excellent plugin! It really helps organizing and speeds up the site.
My only problem: NextGen Gallery stopped working. I went down the deactivate all plugins route to find the one that causes the conflict and I found out that it is Plugin Organizer.
This is 100% sure I have to say because:
1. All plugin deactivated = NextGen works
2. All plugin activated except Plugin Optimizer = NextGen works
3. All plugin activated including Plugin Optimizer = NextGen dead
4. All plugin deactivated only Plugin optimizer activated = NextGen dead
The error message I get when I try to use NextGen's settings via the admin panel and the two plugins clash is:
'You don't have permission to view this page'
Can you please help, as I would like to keep both plugins!
