Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
You must have received an email from WordPress with the details about the error. Please share it with us here so we can check and assist you further.
If you haven’t received the email with the error code, you can follow this guide to enable debugging in WordPress
https://wordpress.org/support/article/debugging-in-wordpress/ or you can get in touch with your web host, and they will help you locate the log file.
Having an error log will help us determine what is causing the critical error on your website.
You can trigger again the error so the log would be updated.
Looking forward to helping you.
Thank you.

Hello,
The issue seems to be related to the action scheduler. Please follow this guide and ensure that you first take a backup of your database:
1. Please follow the steps from this KB guide to fix the issue:
https://rankmath.com/kb/fatal-error-after-1-0-49-update/
2. Please follow only the first 2 steps and clear your caches. The following steps mentioned in the article are for advanced users.
Here’s a video screencast:
https://i.rankmath.com/KStFug
Please clear all the cache, including the server after following the above process.
As for the rest of the errors, I noticed a constant PHP Deprecated issue.
Please make sure that you are using the preferred PHP version of your website and we recommend the stable version PHP 8. You may contact your hosting provider with regard to updating your PHP version.
Please refer to this guide about our plugin’s system requirements: https://rankmath.com/kb/requirements/
Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
Thanks Jeremy,
I have followed your steps but the problem was not solved.

I had to disable it again.

Hello,
What is failing on the website is a default PHP function called error_log() which WordPress uses and we also make use of it to show the error log to the users in the Status & Tools section of the website.
This error indicates that this default function is not working in the PHP runtime environment. You can check this with your hosting provider and ask them to make sure this is enabled on this particular server configuration.
Hope this helps solve your issues.
Don’t hesitate to get in touch if you have any other questions.
Excellent, our hosting provider enabled the error_log() and now it’s working
Thank you for your help
