FATAL Error after WP 6.1 update

Hi
Same with me!

Same here, any way to resolve this?

I’ve seen this earlier today on a site, but it was after updating another plugin. Actually the client probably updated multiple plugins at once. If you remove the plugin you updated last via FTP or your hosts filemanger, you can login again and reinstall the plugin. It should probably work.

Same here!

*mailpoet – sorry for the typo my friends.

Same here, had to deactivate.

Thank you everyone who reported this issue! We are currently investigating and working on a fix.

To help us tackle the problem quicker:
1. Could you please post a list of WordPress plugins you have installed.
2. Could you try to downgrade to an older MailPoet version (3.101.1 – can be downloaded here) and see if it helps?

MailPoet Team.

Tested the previous version:

// enabling auto-updated worked this time.

// Fatal error again. Below is the error note. xxx – censored info.

SOLUTION: The Error was caused by using a 5.6 database on one on the sites. Other sites with a 5.7 or better 8.0 database did not experience this issue.

Actionpoint: update the database to 5.7 or higher (8.0).

This should solve the issue. Enabling the PHP extensions POD, PDO_MYSQL, XML and ZIP as well as mbstring is necessary.

Wishing everyone a quick fix.

Hi there @mishoo28 , thanks for the update.

I have just passed your info to our developers. They are currently working on a fix for this issue and we’ll update this thread as soon as we have any news.

Thanks for your patience.

Cheers

Hey again @mishoo28 !

Just a note that we have a hotfix version of MailPoet coming out to fix this.

I won’t bore you with too many details, but basically WordPress 6.1 changed how it handled normalizer and some other pieces of software are not happy about that.

Here’s where it’s being chatted about for a WordPress bug fix:
https://core.trac.www.ads-software.com/ticket/56980

There’s a couple things you can do in the meantime while waiting on a MailPoet release:

immediate fix: downgrade to WP 6.0
long term solution: install intl extension for PHP, then upgrade to WP 6.1

Or you can just wait for the MailPoet release, which should happen just a bit later today.

I spoke just a tiny bit too soon!

Here’s the link to download the latest version of MailPoet (or just run the updater in your WordPress site): https://downloads.www.ads-software.com/plugin/mailpoet.3.102.1.zip

Thank you SO MUCH for your speeding update!
