I'm using WordPress 2.7 and have been for a while. Recently though when I tried to make a post it started acting strangely. When I load the admin page it appears briefly and then the page suddenly goes white. My Firefox tab says "Loading" and it just hangs and never loads anything. If I hit the stop button really quickly as I log in sometimes I can make a blog post but whenever it goes to save a draft I am asked if I want to navigate away from the page and then it does the same thing hanging on a white screen that says "loading". Aside from blog posts I've not changed anything lately, so I'm wondering what's up. I'd appreciate your help!
