Fatal Error after Rank Math Update

Hello,

We apologize for the issue you are facing with the Fatal Error after the Rank Math update. This error seems to be related to the Action Scheduler, which is a component used by Rank Math.

To resolve this issue, we recommend following these steps:

1. Backup Your Database: Before performing any actions, ensure you have a backup of your database. You can find guidance on how to do this here.

2. Use the Repair Action Scheduler Plugin: You can use our Repair Action Scheduler plugin to fix this issue automatically on most sites. You can download it from this GitHub link.

   • For multisite installations, use the files from this link.
   • After downloading, upload the ZIP file to your site via Plugins → Add New → Upload Plugin.

   

3. Activate the Plugin: Once activated, the plugin should automatically fix the issue and deactivate itself. You may see messages indicating that tables have been created successfully.

4. Clear Cache: After following these steps, make sure to clear all caches, including server cache, if applicable.

Hello,

Assuming you are using the latest version of all the plugins and the themes (please update if not yet), this can be caused by conflicting plugin/theme on your site.

To determine that, please follow this troubleshooting guide:

Looking forward to helping you.

Hello,

Thank you for contacting us. We apologize for any inconvenience this issue may have caused.

Cueing from other users where this issue was investigated, we found that it is happening due to the conflicting ActionScheduler packages used in the plugins on the site.

It is likely the Mailpoet plugin is using an older version of the ActionScheduler package, while our plugin uses the latest version, v3.9.1.

Since it’s on an external plugin, Mailpoet will need to update this package in their plugin.

Kindly reach out to their support team concerning this issue.

In the meantime, you can install and activate Action Scheduler by Automattic.

If you install that plugin it should manage the ActionScheduler package instead of the individual plugins’ versions being loaded.

Let us know how it goes. Looking forward to helping you.

Thank you.

Hello,

Some other users have already reached out to MailPoet and this is an extract of their reply a user shared with us:

… it’s actually something that can be replicated any time Action Scheduler 3.9.1 is present but loaded after an earlier version. We’ll look into a fix on our side.

Lending your voice/vote to the issue might move its priority up the scale.

Just as we stated you can use the Action Scheduler by Automattic in the meantime.

Don’t hesitate to let us know if you need our assistance with anything else.

Hello,

We are glad we could address your concern.

Please feel free to create a new forum topic if you do have another question in the future.

It will be our pleasure to assist you again.
