I installed NG from Photocrati.
At first everything went well for uploading pics.
Then i loaded more then 20 pics, so they were placed on 3 pages.
First page was accessable, 2nd and 3rd not, url was changed.(cant show it anymore because plugin doesn't work anymore!!! See below))
On the enlarged pics itself, there were no forward or backwards arrows to navigate, neither a cross to close.
When i changed my small letters to capitol letters @ my pics, i had to save it twice before i saw the change.
Further on, i tried to erase Permalink slug (nggallery)(for reason above about changing url), which worked, but when i pressed Save, i was redirected to my homepage and every link i tried in my menu was also redirected to my homepage.
When Nextgen Plugin was deactivated, everything was back to normal.
Also, it's not possible to enter that permalink slug again or another one.
I did deactivate all my other plugins, and activated them one by one, but no result.
Site is ok for the moment, but Nextgen is deactivated.
All "errors" occured in the order i wrote them down here.
So what's going on here???
