Hello,
send me an email saying that the problem is due to another theme, it's not serious ...
Please stop saying that the problem is something else, it's not like that ...

The problem tests have been done by my server hosting, which point out to me that there are numerous problems that I cannot attach here, because I am limited by 2000 characters, so I cannot attach all the results bag.

Kindly do the test too, the site I attached earlier is a test site (https://shop.milani6.com/), the actual website is https://www.milani6.com.

take the test on: https://developers.google.com/speed/pagespeed/insights/, enter on: https://www.milani6.com the result is:

Lighthouse returned error: FAILED_DOCUMENT_REQUEST. The requested page could not be reliably loaded in Lighthouse. Make sure the verified URL is the correct one and that the server is properly responding to all requests. Detailed information: net :: ERR_TIMED_OUTIgnore

If you take the test on http://test.milani6.com/ which is a subdomain, the result is: perfect ... even if it's just wordpress ...
