I updated to 3.4.1 several days ago after seeing the notice on my dashboard to do so.
Now I can no longer edit any posts (page comes up blank), edit/customize my theme, get to my plug-ins page, and so forth.
I can log in as "admin" just fine and can basically get around, but I seem to have a frozen site now as far as doing anything.
The site is not having a problem on the reader's side.
Any clues or suggestions?
Thank you very much to anyone who can help,
