Hello,
We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.

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:
https://wordpress.org/plugins/temporary-login-without-password/
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):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
I have checked it and meanwhile, it is just a warning and it is not causing any issue in your site (nor rankings), you could read here more about how to fix: https://stackoverflow.com/questions/8028957/how-to-fix-headers-already-sent-error-in-php
But as I said, it is fully optional and not necessary since it is not causing any issue.
Looking forward to help you.
Hi,
I tried to follow the instructions contained in the link you posted to resolve the warning, I opened the three .php files mentioned in the error log generated in Rank Math> Status & Tools looking for one of the seven reasons that are mentioned in the post that may cause the error (or warning).
Six of these reasons are not applicable to my three .php files, one this, I quote, “To avoid this, simply leave out the closing ?> – it’s not required anyways” could be applicable because all three files contain the closing tag but not the accidental white space, foreseen in the cause, before <? php, so I didn’t feel like modifying the three original files, also because I don’t know if the next time the plugin is updated the problem will recur.
At the moment I leave everything as it is, what about Seo Analysis where the total number of tests changes, is it normal? And for the freezing screen?
Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
The SEO analysis tests are usually out of 30. I have done analysis on your site a number of times but I can’t replicate the issue.
In the issue of freezing when you follow the steps: WP Dashboard> Rank Math menu> Status & Tools> Advanced Mode> Click on Database Tools> Last click on Easy Mode, it is likely because the database tools are not available in Easy mode. I have however notified the dev team on this for further investigation.
Looking forward to helping you. Thank you.

Seo analysis does not always change the total number of tests and I have not been able to replicate the issue, I will try to do it several times in these days, if the error occurs again I will take a screenshot and send it to you, for this I will keep the ticket open a few days.
