UPDATE 04/16/2015 DONT DO THIS, READ POSTS TO FIND OUT WHY!
Just go to your phpMyAdmin and run this sql
UPDATE `ow_base_plugin` SET `isActive`= 0 WHERE `isActive` = 1 AND id > 3
everything under 3 you need like admin panel and ow base, every over 3 should be ok, just check your install plugins afterwards, if you get a blank page just look at your table, sort it by id, and look at the first couple of items, you may have turned off something you need, if so just edit it and put the 1 back in isActive and your all set.
Much quicker than doing it one by one..
When you re-activate sorry you HAVE to do it one by one, because your checking for errors and issues along the way... sorry cant help you with that, we are all stuck with that one.. :)
