Hi Jasonargo,
Regarding your issue, it seems like your site is very unstable. When i visit your site, very often i hit this error message no matter which page I am at your site frontend.
Error displaying the error page: Invalid JDocument Class: Unable to load renderer class
If i refresh the page, then the above error disappear.
Also, I getting alot of these error message when I enabled the Joomla error reporting:
Fatal error: Call to undefined function utf8_ucfirst() in ..../libraries/joomla/string/string.php on line 700
Fatal error: Call to undefined function utf8_ireplace() in ..../libraries/joomla/string/string.php on line 306
For the above errors, I've modified your file 'JOOMLA/libraries/joomla/string/string.php' at line 46 and 47.
Please see

The original code is using jimport to add the phpuft8 libraries and it seems like it dont alway work. So i use required_once() instead. The fix i added seem fixed those undefined function error messsage.
Another thing is, when i at your site backend, very often i hit this error:
Fatal error: Class 'JPath' not found in JOOMLA/libraries/joomla/cache/controller.php on line 161
Did you recently upgrade your php version or your Joomla version? Can you check your apache if there is any error log? I've checked your Joomla error log and the error logs are not useful. Maybe you can check for me on your server side the error log and see if it logged any fatal error?
Please advise.
