I had to update a couple of my other websites as they were older versions to 3.1 and they are working fine now. The 2 websites i had which didn't need updating i am now having issues with ( which could be totally unrelated). When i view the website
http://www.fixcleanerreviews.org/
it views as normal you can see my 4 posts on the main page, But when i log in to admin and try to edit a post. I can see the heading but the post section is totally blank. There is an error message on my computer bottom left hand side with the yellow error triangle when i am logged in saying page error, and when i log out it dissappears. I seem to be able to click on each post but all of them on both websites you cannot edit or type in any way. I can't even click on the html button, nothing happens.
Can anyone shed some light as now i cannot alter my website in anyway
