I have installed the Leviathon template, and want to make some customizations (ie add a background image, change some of the color settings...). When I click on the Leviathon Style in Template Manager, I get "An error has occurred. No HTTP response code found.". My only option is to "Return to Control Panel".
1.) Changed Update server from Short Term to Long Term, got the same error (then switched back to Short Term). I've already updated Joomla at lease once, so I am guessing that this is not the issue.
2.) The only plugins I have installed are Easy Folder Listing Pro, and JCE Editor.
3.) Not sure how to check/trouble shoot this, am a newbie.
I changed the error reporting to Maximum and then to Development - got the same error with both settings. Any further assistance you could provide would be greatly appreciated.
