Hello,

Please I need help installing xenforo on my server.

When I get to the https://ask.ngscholars.net/install/index.php?install/run-job stage, I get the following error:

LogicException: Entity XF:CodeEvent (class: XF\Entity\CodeEvent) could not be found in src/XF/Mvc/Entity/Manager.php at line 51
