Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
I’ve checked your website sitemap, and it seems the error 500 is only happening in page, post and category sitemap. In this case, could you please reach out to your web host for the error log for us to determine this issue’s root cause?
Thank you, and looking forward to your update.
I’ve investigated the error log for Rank math, and noticed that there is an issue with a line of the code of the plugin:
> line 444
Below I provide you with the entire error log:

I will advise you to review the website with Rank math, as they can provide you with the necessary information on the matter, as I earlier said.
Hello,
I checked your site and it seems the plugin was not installed correctly and some files were missing.
I re-installed Rank math on your site and now the sitemap seems to be working as expected, here is a screencast from my end: https://i.rankmath.com/u4S6Gm
Please check this from your end in a private/incognito tab to confirm this.
Hope this helps. Thank you
