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.
Could you please check your website’s error log when the issue happened? You can get in touch with your web host for assistance with that information.
Meanwhile, please ensure that your site’s PHP values are not too low. Please get in touch with your web host and ask them to set the following values (if not yet):
PHP Memory Limit: 512M
Max input time: 150
PHP time limit: 120
PHP max input variables: 1000
Looking forward to helping you.
Thank you.
Hello and thanks for the quick reply, I checked,
here are my parameters:
Variable PHP maximum input 12000
PHP 300 time limit
PHP 512M memory limit
Maximum input time 300
Error log of today:
[Mon Feb 28 17: 20: 49.023879 2022] [access_compat: error] [pid 7234: tid 23392136591104] [client 185.221.174.50:35254] AH01797: client denied by server configuration: /home/kigijdqb/public_html/xmlrpc.php, referer: https://www.eventiglobo.it/xmlrpc.php
Obviously if I disable the Rankmath plugin everything will work normally again.
How could I go about solving the problem?
Thanks in advance.
Hello,
In this case, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
Thank you.

Hello,
Thank you for that information.
I’ve checked your site, but I’m unable to replicate the issue upon editing some of your posts. Please check the screencast attached in the sensitive data section and let us know if we’re missing some steps to reproduce the issue.
Looking forward to helping you.

Thank you.
Hello,
I was able to replicate the issue on your site. The issue is being caused by a long keyword in your focus keyword field:
Discoteca La Villa Aperitivo Djset venerdì 4 marzo 2022
We recommend that you try to use smaller focus keywords to prevent issues like this in the future.
Don’t hesitate to get in touch if you have any other questions.
Yeah! Now working fine! Thank you and have a nice day!
