Hello,
Thanks for getting back to us.
The issue of the missing H1 tag you can easily fix by adding an H1 tag to your homepage anywhere you want. At the moment looking at the source code we can’t find that.

Regarding your image issues, this is not possible to fix with your current setup because those images are being last loaded and the function that adds the missing alt tags runs before user interaction. Since the lazy load of images requires user interaction to trigger the images appearing on the page the function won’t run on those images.
Lastly, the unminified CSS there’s also no solution for that because that file is coming directly from a CDN and we don’t have control over that.
Hope this helps clarify the situation and solve the missing heading issue.
Don’t hesitate to get in touch if you require any further assistance.
The PHP has been updated to version 7.4.
I am not sure how to add an H1 tag in the homepage.
Hello,
Thank you for the follow-up, and sorry for the delay.
In this case, you may need to coordinate with your theme provider/developer on how to add the H1 tag to your homepage as your website is still missing that tag in the source code.
I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
