Disable jetpack for spreadplugin and check why your https certificate is revoked – if you use it ??

Thanks for the advice!
I deactivated Jetpack completely, but I still have the same issue.
( even after rebuilding shop )

I’m sorry, but as long as I can’t access your website, because all resources are trying to open it via https, I can’t debug it.

SSL Certificate should be now back online.
Is it available for you?

You have a javascript problem in one of your scripts:

108rotate.js?ver=1.0.0:11 Uncaught TypeError: Cannot read properties of null (reading 'style')
    at HTMLDocument.<anonymous> (rotate.js?ver=1.0.0:11)

it’s preventing from other scripts to run.

And please read the error log of your server, WordPress is reporting error 500.

I tried this, but same error.
The debug is saying something like :

Interesting, it should only raise a warning, but this is fixed in latest update – you should have it already if you try to update plugins.
