Astra Website menu missing & homepage messed up

Hi!

The error is with the Astra Theme. I didn’t change anything about my website. I even tried to restore from a backup that I know was working, each time I get the same issue.

after the restore from backup it even looked normal. Then after a minute or so (after logging into wo admin and doing nothing else there), it returned to this messed up state.

The header is simply missing and I have a huge image of my logo where it shouldn’t be.

it can’t be because of an update as the plugin should sport an old version of astra..

I’d appreciate any pointers!
