I cannot post updates, edit categories, upload anything, and my admins cannot login to wordpress. My hosting server is running great, it's still up and secure as always, the site is still displayed properly. I thought upgrading my WordPress would resolve this but i can't even do that. It'll ask me "Are you sure you want to do this?" and it has no buttons for yes or no.
When i try posting something new, I'll click publish and it'll return to the same post screen with all the text fields blank.
What is going on???
