I'm nearing the end of my patience with this problem that has spawned many other problems.
First off, I can't upload any photos to my blog. It always ends in an "http error" when using the flash uploader or a 500 error when using the browser uploader. I have scoured the WP forums and Googled the issue for HOURS with no luck. I have tried all sorts of htaccess edits, hacks and upload tricks with no luck.
Now in all my troubleshooting other quirks are surfacing such as plugin installations stall. Some plugins install ok but most stall and require manual installations. Also, something else I just noticed tonight in my troubleshooting of the http error, now the installed plugins page is blank and many of the sections of the dashboard are missing even though they are checked off as enabled.
I'm at a complete loss here. I just want my old functionality back I had with 2.6.
