I‘ve been experiencing quite a strange issue with my WP website since I’ve upgraded my WP to the version 5.4.2.
From time to time (it can occur to 2-3 times / week) my Website is displayed as html Code on all the devices / in all the browsers (pls take a look at the Screenshot). The problem disappears as soon as I log in into the WP dashboard - no further actions are required.
I‘ve checked the plug-ins - they are all compatible. There are also no errors detected in the WP Website Status.
Has anyone any hint for me what could cause such a problem?
Thanks in advance.
