@exatechgroup: thank you! ??

I took the time now to check, with which version my listed errors are shown in dashboard and Mailpoet stops working:
5.1.0 -> all good, no errors, plugin works fine
5.1.1 -> all good, no errors, plugin works fine
5.2.0 -> all good, no errors, plugin works fine
5.2.1 -> all good, no errors, plugin works fine
5.2.2 -> errors, plugin doesn’t work, not able to create newsletter etc.

BUT:
After updated to 5.2.1, WordPress sent an email (“your site has a technical problem”) with the following error, but I still was able to work with the plugin:

An Error Type E_ERROR has been caused in line 77 of file /var/www/vhosts/trackdays.sina.hostkraft.de/html/trackdays/wp-content/plugins/mailpoet/lib/Util/Notices/PermanentNotices.php.

I hope, I could help with this information, so the support is able to find out, what causes the error(s).
Errors seem to be caused by one or more files that were updated from 5.21 to 5.2.2.
Because 5.2.1 works so far and is able to access the database correctly, it looks like the DB is ok…

I will work now with 5.2.1 until an update will fix the error(s).

//You can also share the version of the database used on your website.

My database version:
https://www.trackdays.de/dl/Screenshot 2024-10-11 111304.png

I urgently need to send a newsletter in the upcoming days.
So I need possibly to downgrade before Mailpoet 5.2.2.
Where can I find older versions? Will there come up problems because of downgrading?

// The query returned no results. I see, there is no auto_increment entry in Column Extra
at table 'wp_mailpoet_newsletter_option_fields':

Could you let us know if you have recently used any plugins or tools for restoring your database, migrating between hosts, or similar actions?
// No. Every other plugin etc. works fine, no errors, beside Mailpoet.

The problem first occured after updating to Mailpoet 5.2.2.
I never had any problems with Mailpoet before.

Mailpoet updated to 5.3.0 (my WP version is 6.6.2 – german version), same errors as listed in the 1st post.

1. Create a backup of your website.
   // Done
2. Update WordPress to the latest version (6.6.2)
   // already installed before Mailpoet Update (see 1st post at the begin)
3. Could you please follow the instructions to?re-install the plugin via FTP?and let us know if it resolves the issue? This will ensure no plugin files are missing or corrupted.
   // Done, same errors on dashboard / Mailpoet
