XF 1.4 ErrorException: Undefined index: permissions - library/XenForo/ControllerPublic/Watched.php:218


Well-known member
I gut this Error and several others, everytime it's Undefined index: permissions in sevveral Files, like Alert, Watched Forums, etc.

I reordered some Forums and deleted one last Night.

I took a look into the database, if there is any old node_id inside the watched Table with no corresponding node_id in the node or forum Table, but the data seems not to be corrupted.

Do you have any Idea, what else can I check?

IIRC, this is usually something that isn't actually possible in the code. Which leads to it being triggered by a corrupt opcode cache.

Try clearing your opcode cache to see if that helps.
