Every time I try to edit my signature lately, it says changes saved successfully, but when I leave the page it completely erases my signature. When I go back into the edit box, it's blank as if I never posted anything period. What's up with that?
I signed off and then signed back in and this seems to have resolved the issue... EDIT - Not really. I tried changing it again without signing out a second time and the glitch occurred again...
Alright, after fiddling around a little it looks like it's the gallery add-on causing it. I've temporarily disabled the gallery and will look into it further. For now you should be able to edit your signatures.
