From what i am able to tell, a .css file is either not working, missing or just being an arse. This is causing my dashboard to display just a very basic HTML style. Basically making managing and updating my website impossible.
I have tried,
Clearing cache for browser
using different browser
trying on different machine
disabling all plugins
reverting back to twentythirteen theme
Fresh install of wordpress
None have fixed my dashboard.
I even went as far as to create a fresh blog to see if the problems where replicated there. The dashboard was normal on the test blog. So i feel the error must be local to my install.
I have now restored complete site using a backup i know was perfect at the time. still no fix.
