All of a sudden I can no longer edit in wordpress

I was in the process of updating my website. It worked one day and the next day I went to modify a page and the Hyperlink, and text editor are not working. I just click it and nothing it doesnt even change... Multiple browsers and computers tried.

I do not know if anything auto updated. Trying to find the fix. Not a WPMU problem but i do have wpmu on it. I had not added anything before it stopped.
