The website I run encountered an issue today caused by a plugin. My webhost disabled the plugin folder by renaming it. They advised that I rename each plugin folder in turn to find which plugin was causing the website to not load. I was in the process of doing this, when the website went live again but without the plugins working.
Then the backend has now lost its structure and looks like this: http://snag.gy/UUO1p.jpg
I've reinstalled the current version of wordpress but to no avail.
Can anyone suggest what might be causing the backend to do this, and why the plugins are no longer working?
