9.2.0RC1 Call to undefined method Concrete\Core\View\View::isEditingDisabled()

I installed 9.2.0RC1 with PHP 8.1 (same error with PHP 7.4) on my test site and I now get.
Call to undefined method
Concrete\Core\View\View::isEditingDisabled()

If I am logged in it show the page proper, but nothing is clickable. When I log out, I get:
/updates/concrete-cms-9.2.0RC1/concrete/elements/header_required.php
Error on line 196 “if (!$v->isEditingDisabled()) {”
The dashboard works fine.

Hi @mdius - this is just a vanilla 9.2.0RC1 install - you don’t have any overrides or packages included?

I have several packages and a few overrides

Maybe I should add, everything worked perfectly on 9.1.3.
Sorry, I didn’t give to much info in my original post.

Got it - have you overridden /elements/header_required.php by any chance? There might be some things that have changed in 9.2 that the override needs to be updated to accommodate - that would be the first place I would think to look.
