XenForo_Model_Tag::getTagResultsForDisplay() can return false, but XenForo_Controller_Tag::actionTag() doesn't check the return result.
This can lead to trying to-do a foreach() on false rather than an array, which fails. This is probably due to a custom tag handler not behaving as expected or having been removed but the custom tags are still in the tag tables.
Example error:
Note; Tag Essentials just calls XenForo_Controller_Tag::actionTag() as it's first step.
