Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
1.
HTTP Error:
404
In the case where you are getting a 404 error. Simply head over to your WordPress admin area and go to Settings > Permalinks and hit the “Save Changes” button once even if you didn’t make any changes on the page.
Then head over to Rank math > Sitemap and chit save button once.
This should fix the issue.
2.
site map is html
Make sure that you submitted the correct XML sitemap to Google. You should submit the sitemap available on your website at https://domain.com/sitemap_index.xml
If you are sure you submitted the correct URL but you are still facing this error, check for a plugin conflict using Health Check plugin.
If you are running W3 Total Cache along with Rank Math on your website, make sure you create another user agent group and add the ‘googlebot’ user agent to it.
Looking forward to helping you. Thank you.

Hello,
The Cloudflare cache is still active on your sitemap file. Could you please temporarily disable it Cloudflare caching for your site and check if this issue will still be replicated?

I have also set as excluded your sitemaps in the cache plugin you have on the website, since it was also caching it.
Let us know how this goes. Thank you.

Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
This is bit odd, it may suggest a communication issue with your database. Would you mind letting us know the kind of errors that you are experiencing while using the plugin that are prompting the need to clear transients?
Looking forward to helping you. Thank you.
well all issues are solved now and i don’t need to clear transient for any specific issue for now
but the option is still not working
if its not working then there is issue with the plugin.
if you could please check the site with provided credentials, it would be of great help
if you still want to know the issue,
the issue is with the addition of brand attribute to products. i had added brand to products but the schema is not being updated for rich result.
i guess schema structured data ain’t being updated and wanted to clear transient files so i might able to narrow down the cause
Hello,
The temporary link you provided doesn’t seem to work for me.
The option to clear transients should be working with the latest plugin release. Please ensure you have updated your plugin.
I have checked your site on google SDTT and there doesn’t seem to be any error or warning. Please let us know if what issue you are currently facing if any.
Looking forward to helping you.
Hello,
