This is happening again
When I press on 'Select Theme' noting happens. When I select 'Edit Theme' I get a blank page. This all happened after I manually renamed a backup theme folder to my Live theme name and the live theme name to a backup name, I reverted back later. Permissions are all set to 777. ??
On IE I get the error:
The website cannot display the page
Most likely causes:
•The website is under maintenance.
•The website has a programming error.
What you can try:
Refresh the page.
Go back to the previous page.
This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.
