I am having an issue with a Xenforo installation (1.1.3) hosted on one of my servers.
When attempting to rebuild the Search Caches, it stops with an "Error has occurred" then spits out this PHP Error message.
Fatal error: Class name must be a valid object or a string in /home/*****/public_html/forums/library/XenForo/Search/DataHandler/Abstract.php on line 543
The Xenforo File Check shows up negative, and all files are correct.
So any ideas as to what the issue could be?
If you need any further details let me know.
