XF 1.3 XenForo Callback (Invalid Class) issue.

#1
Hi guys,

I have problem with my XF, everytime I want to install an add-on, I got these 'Invalid Class' issues:

When installing Tapatalk:
Error
Callback Tapatalk_Listener_LoadClassMail::loadClassMailListener is invalid (Invalid Class).
When installing another add-on:
Error
Callback ReckonsTeam_GoogleCustomSearch_Listener_LoadClassController::extendXenForoSearch is invalid (Invalid Class).
Any idea what's wrong with my XenForo?

I did Tools -> File Health Checks: All 1.125 checked files are present and correct. :)

Any solution would be appreciated.

Thank you.

This would indicate the files haven't been uploaded to the correct places (or properly). You should contact the relevant authors/post in their add-on threads so they can give specific comments on how their add-on is packaged.
