I just went to check my blog using Firefox (which I normally use) and all it says is "Not Found." The dashboard shows 0 posts and 0 pages! I panicked but then went and checked it in Safari and the blog is there. I haven't dared log in to the dashboard in case it all disappears. The only new thing I installed today was the plugin Snazzy Archives. I disabled and deleted it after this issue arose but there is still nothing in Firefox!
Thanks for any help you can provide!
PS. I also tried emptying the Firefox cache but it didn't help.
