Totally fucked up my site

Ruined my site!

Even i only tried the demo mode… it changed the wordpress site itself and i could not access any parts of my blog.

I managed to get my blog back to previous state by deactivate all plugins from ftp by renaming plugin to plugin_

Then by ftp also i copied all files from my previous blog to /wp-content/plugins/really-static/static/ then i could get into my wp-admin and the old deleted plugins was back plus the new ones was not there so i could safely delete it and go back to my previous site.

Hope you can get rid of it too good luck. And for everyone else stay away.
