Website: insulatedvinylstormwindow.com
Last week I upgraded to the newest 3.3.1 version and it worked fine, on all computers everywhere. Yesterday, I downloaded an SEO plugin and it worked fine still as of this morning until my computer froze. I shut my computer down, restarted it did a disk-cleanup then went to my website. I wouldn't think that that had anything to do with it since the website is on a server and my computer is not. My website wouldn't load except fotr the background. So I went to login to see if I can find the problem, and I couldn't access the wp-admin either. I checked Firebug to see what errors it said it was having and it was giving me a 500 internal server error so I contacted my host to see if it was an issue on their end. It wasn't and he said it appears to be a wordpress issue.
Then I took my backup and uploaded it via FTP and hoped that it would work (which was backed up before the version upgrade and the plugin). It didn't. Firebug I can access my pages if I make it go to the 404 error (such as going to insulatedvinylstormwindow.com/wordpress/test) then I can access everything but the home page and get into the admin. If I do that my url becomes really long ie: http://insulatedvinylstormwindow.com/wordpress/http:/example.org/categories/gallery/video/ so I can't access the subsequent pages just by entering in the url. And Firebug still gives the 500 Internal Server Error. I tried changing the url to /wordpress/wp-login.php, which shows up but once I enter my user name and password it goes blank.
I tried renaming the plugins folder to plugins2, but it wouldn't let me.
So is there a way of disabling the plugin without going through the wp-admin?
Adjusting the permalinks also without the wp-admin?
Reinstalling wordpress, without losing information, through an ftp?
Or any other suggestions you may have.
