This is what is listed under plugins (I note there is a blank entry that is blank under title, says Version - author under description and has an option to enable. Not sure how I can remove a blank plugin but Im sure its causing problems!):

Also, how do I go about upgrading GetSimple without losing any of my content? Are there particular files to backup then just overwrite the current files with new ones then transfer the config files back (if that makes sense?!)
