Hi @richardcreative,
Thank you for writing in, and sorry that you’re having that issue. Did someone edit your homepage outside of the Content Builder? Because this autosave will not show up if it’s not edited outside of Content Builder. I saw other pages that become this as well so there is a possibility that a bulk edit page has done. If this is the case, you need to use the page revision to restore the page on the previous date.
And yes there seems to be something going on the header as I can’t even see the Edit Text option of the Headline element
I see that you still have plenty of plugins enable. If you can not deactivate those plugin because this is a live site, please clone your site to a staging server and provide login credentials (wp-admin and FTP) of that staging server so we can investigate further.
The Modern Events Calendar is even weirder because you can see that you have a number of events, it just not showing on the table.
When you’re updating the Pro, WordPress, and all plugins, did you encounter any issue maybe the update has been interrupted and some of your files had been corrupted?
Please try reinstalling the Wordpress, you can do this under Dashboard > Updates, you can see a re-install button there. Also, reinstall the PRO theme.
Let us know how it goes,
Cheers!
