Hi Rikard,
Thanks for responding!
Unfortunately, the problem has been (seemingly) random at this point. The first time it happened immediately after I edited a page from the front end by clicking “edit page” on the admin bar. Afterwords, it seemed to happen evem when I was not logged in and doing anything.
Is there some suggestion you have about either checking logs to see any weird activity or adding a debug log to see how i could replicate the issue and check error output?
