About a week or two or so ago I updated my wordpress to 3.7.1 and at the same time All in One SEO pack just vanished from my admin panel. It doesnt show on plugins page at all. However it shows on the server when logging on with FTP and when trying to reinstall it starts to install it and then gives out error;
The folder already exists.
Installing plugin failed
(Messages originally in finnish but the meaning translates like that)
Its annoying since my page has since skyrocketed down on google from first page to 3rd on most popular search words. I also paid quite deal of money to person to set me up with SEO so I dont want to just delete the old files and lose all my settings.
