Am haveing a problem with activating alot of the plugins. When I install my plugins by ftp client and then try to activate them it goes to a error 500 - Internatl server error. So i went to my server provider for help and they said that my wordpress was installed fine and that it could be a version issues, but i dont think so becase buddypress is updated. So what else could it be. I am also using default theme.
