Since nearly mone month ago (when on 2.7), my admin panel showed a very strange phenomenon.
When I logged into the admin panel using IE, it hang there and died, nothing happened. When on FF, chrome, I loged in, but very strangely the admin panel loaded multiple times inside the same windoe, each admin panel of them inside the first one ! And here, none of the admin sections worked, all links keep redirecting to the admin panel index.
Since a week ago, while the first problem persisted, the index used to load, but posts/pages/archives/cats links brought into 404 page.
A day ago, even the index started not to load and bring completely blank screen. When logged into the admin panel, it succeeded, but after that I get "not authorized to view this page".
I dont know what to do !!
Before the last problem, tried to recognize if a plugin causes the problems of 1 and 2 , and started disabling them by renaming their folders in the ftp (because I couldnt use the admin panel). When I renamed that of "WP-Super-Cashe" , the blog's index didnt show up at all, despite the plugin is originally inactive since the past before any of the problems occured. This might not be related, but it is worth mentioning.
