After a year of working correctly I have run into a real problem.
The website displays correctly but on going to the admin area and attempting to edit a post this happens:-
The editing area is apparently blank. I say apparently because if I drag the cursor over the area the text shows, highlighted in blue, in HTML format.
No toolbar shows.
The Visual and HTML tabs do not work.
The upload media buttons do not work.
The same things apply also when I try to create a new post.
This happens in Firefox, IE, Chrome and Opera browsers. I have disabled all plugins, switched to default theme, Used FTP to rename the plugins folder and updated to 3.4.1. None of these have made any difference to the problem.
This first happened before updating to 3.4.1
Where do I go from here please?
Thanks in advance
