After an accident that caused me to delete the wrong files, I re-uploaded the files for my forum. It appears, however, that it didn't quite work as well as I thought because I'm experiencing the following error:
Fatal error: Class name must be a valid object or a string in /home4/**********/public_html/community/library/XenForo/Model/Node.php on line 521
Any idea what this issue is trying to tell me? Thanks!
