When editing, I cannot do anything. I cannot update posts. I have tried disabling all plugins with no avail. I've used all of the default themes. The browser does not matter... I've cleared the cache, and history on all browsers -- Firefox, Internet Explorer, Chrome. Word count is 0 on all browsers, after logging in, and the "Visual" tab looks exactly like the "Text" tab. This happened randomly. I'm well versed in IT, and I normally never ask for help.
I'm fairly certain that I need to reinstall WordPress, but I'm trying to avoid that. I don't really care if I have to do that, but I don't really want to. Yoast's SEO plugin is not accessible, no matter the circumstance. What do you recommend?
