I updated a client site a few days ago and she has just tried to write a blog post, but the wordpress editor has disappeared from the post page. Furthermore I cannot select the "Text" version of the post or any page.
The content of previous posts are sill present on the front page but the default text colour appears to be white and the editor functions are just gone.
I have re-installed v3.5.1 and changed the active theme, disabled all the plugins, nothing works!!
any help would be appreciated.
