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.
5xx errors are usually caused due to server misconfiguration or other server issues.
Can you please share the website error log with us? Having the error log file will give a clear idea of why this might be happening.
Meanwhile, you can follow the steps in this link for troubleshooting the saving issue:

Regarding the page with redirect errors, please share the affected URL/s so we can also verify their status.
You can also check our guide here on how to fix that:

Looking forward to helping you.

Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
The version, I have installed is: 1.0.114
Regarding the pages with redirect errors, here are some affected URLs:
https://shop.soccerwidow.com/product/austria-sports-betting-cluster-tables/
https://shop.soccerwidow.com/product/science-football-predictions-over-under-goals/
https://shop.soccerwidow.com/product/france-ligue-2-cluster-tables/
https://shop.soccerwidow.com/product/spain-la-liga-primera-cluster-tables/
There are more but Google is currently checking them. I would leave it for a couple of days and see if it sorts out itself, especially if we find the problem with that 500 error.
Thank you!
Hello,
I’ve checked the error log you shared, and it seems that Rank Math’s being blocked by your web host’s ModSec (Mod Security) feature.
Here’s a link you can follow to fix the issue:
https://rankmath.com/kb/settings-not-saved/#num-3-due-to-modsecurity
Regarding the page with redirect error, those URLs are opening fine. You can also use this tool to verify that: https://htppstatus.io

In this case, clear your website’s cache and revalidate the issue in your Google Search Console,
Once done, give Google some time to recrawl your site.

Hope that helps.
Thank you.
Hello,
thank you for your swift reply.
As advised I contacted the hosting provider and asked them to check the ModSecurity logs.
I will let you know asap if that was the culprit and if things have been sorted out or if we have to continue searching.
Have a nice weekend!
Hello,
Sure! Let us know how it goes.
Meanwhile, please don’t hesitate to let us know if you have any other questions.
Looking forward to helping you.
Thank you.
Hello!
Ticket can be closed.
I contacted the hosting provider and they added some exceptions for Modsecurity. Everything works fine now.
Thank you for helping!
Have a nice weekend,
