Sorry if this has been covered somewhere else, I've looked but can't see anything that has fixed my issue.
When I upload a gallery to the page below, I get an error message 'a failure occurred'.
The pictures still upload but the thumbnails fail.
It all seems to have happened after updating to 3.5.1.
I have tried changing permissions to 755 but this hasn't worked. And I have also tried disabling flash mode, and this didn't work.
Any help much appreciated.
