Number of bugs

Note I am using firefox to view the site primarily but some issues are in chrome also.

Firstly the editing of old stacks .

Each time I attempt to remove old titles from stacks I get a message when I save .

I see no problems with what Ive changed yet all I get is a message telling me to choose a template style with no saved changes.

One of my old reviews has a 0.7 score although I want to change the score each time I save I go directly to an error page.

Playing any videos in firefox is now impossible and they simple refuse to play. I get the loading bar on the video screen, then nothing.

Also adding new images doesn't take. I added about 8 images and only three appeared. Then after visiting my image gallery page, all those I added were gone.

I have the opposite problem. My sig didn't come through so I tried it three times. Now I have the three images in my profile. I'd like to be able to delete those but can't find a way.
