Blank page after trying to save a theme
I am also having problems with trying to save any changes in the Design Tab. I get a blank page with the exception of " 0 " appearing in the upper left hand corner. After closing that window, I get the following error in another browser window:
The server encountered an unexpected condition which prevented it from fulfilling the request.
The script had an error or it did not produce any output. If there was an error, you should be able to see it in the error log.
After trying to save changes to a theme - the default theme appears. To get back to the theme I'm using, I have to select it, then edit it in the design tab. Afterwards, I exit the design window without saving the changes.
I also get the same error message when trying to change the logo.
