Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
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.
Let us know how it goes. Looking forward to helping you.
Thank you.
with php version 7.4 work wiht higher Version i become critical Error and i need rename or delete Rakmath bevor i can login to my admin
Hello,
We recommend updating your PHP version to PHP 8.0 because anything below that has reached its end of life:
https://www.php.net/supported-versions.phpIf you are not familiar with this, you can ask assistance to your hosting provider as they will be able to update that.
Let us know how this goes.
With any Php version higher than 7.4, I have no access to my admin dashboard when Rankmath is activated. Currently, I am running Php 8.0
the error only occurs when I activate Rankmath,Stack trace:

Hello,
Thank you for your patience.
The function
error_log()is a built-in PHP function so it seems that the server is using a custom PHP binary.Please make sure that you get in touch with your hosting provider to get you a binary on the website that includes all the default functions from PHP.
This is not something we can fix from our side as it requires super-admin access to the actual server running this website and it’s beyond the scope of our support.
Looking forward to helping you.
