XF 1.1 Moved servers. Now broken

I have done some reading on this and have done a few things.

Config has debug on
An exception occurred: unserialize() [<a href='function.unserialize'>function.unserialize</a>]: Error at offset 0 of 1 bytes in /home/travisty/public_html/thoclan.com/forum/library/XenForo/Model/DataRegistry.php on line 117
  1. XenForo_Application::handlePhpError()
  2. unserialize() in XenForo/Model/DataRegistry.php at line 117
  3. XenForo_Model_DataRegistry->getMulti() in XenForo/Dependencies/Abstract.php at line 134
  4. XenForo_Dependencies_Abstract->preLoadData() in XenForo/FrontController.php at line 125
  5. XenForo_FrontController->run() in /home/travisty/public_html/thoclan.com/forum/index.php at line 13
Then i put this on there as well.
Any help?
