I have setup a brand new joomla 4 site with the example data, directly downloaded from joomla.org. Everything is standard from origin. I have a ssl certificate from zerossl, I got from Infinityfree services. No htaccess tuning yet. No cache.
I try to check the basic performance. GTmetrix tells they cannot acess to the site. Any idea to test ? Thanks for attention.
For some strange reason, GTMetrix requires an intermediate/chain certificate (which is not supported on free hosting) to be installed in order to perform the test, as explained on their site: General GTmetrix Test Errors | GTmetrix
I tried 10+ addresses that I found on the forum and that they belong to free subdomains
and explicitly stated http:// in the address
(and only those that do not force https - no redirection)
and for everything it gave me that error about the certificate
so at first I thought they were blocked.
I think there was a bug with them, because now everything works properly when the http version is requested, which has nothing to do with certificates.
