In this case, please get in touch with your theme provider to modify this H1 tag on your homepage.
I hope that helps.
Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
Hi. I understand it uses the site title as the H1 tag.
Your system is definitely using the recent posts H1 tag also & I can’t find the blank H1 tag anywhere?
I take it you could not find any others except the stit title H1?
Hello,
I checked your site with our External SEO Analyzer and it is passing the H1 Heading test that confirms your homepage only has one H1 tag:

Please navigate to WP Dashboard > Rank Math > Status & Tools > Database Tools and Flush the SEO Analysis Data. Re-run the SEO Analysis and the issue should be fixed.
Let us know how that goes. Looking forward to helping you.
Thanks.
