Logged into admin console this morning, was advised there was a new update for this contact form plugin, clicked to download/install, got 90% complete then said it couldnt remove the old version. No reason why, clicked OK, then my entire site has dissappeared. Cant see the front end, or even the back end admin for WP either. Viewing in IE8, getting an internal Http 500 error. Have sent support ticket to my host, but they reckon there is nothing in the server logs. Any suggestions? Anyone else had this? I can still ftp to my site, if need be to clear out any redundant files etc..
