I am running concrete 9.1.3 with PHP 8.1. For some reason today on one of my sites, I have lost both the sitewide nav bar and the ability to edit and add blocks to my pages when I log in. Also the full sitemap cant be displayed in edit mode and the mobile version has no hamburger icon. All the pages seem to be there however, because when I link directly to any pages they render fine (except no navigation bar).
Clearly something is broken. I rolled the site back to 8 days ago, which is the day before I made the most recent edits. Should I roll the database back also?
FYI, I have 3 other sites running the same concrete version and the same template (Atomik) none of the other sites is experiencing this problem.
Anyone have any ideas whats happening and how to fix it?
