GZip Compression not working

Gzip is not working properly:

“Your server may not have the “deflate” module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)”

I have enabled it in cPanel.

“Another plugin may be interfering with the configuration”

I have done a plugin conflict test.

I have removed everything from .htaccess file. When I try to install I get a lot of upside down red question marks, so I have been adding the code manually, but it still doesn’t work.

I have disabled WP-Rocket and tried to activate.

I have the same problem with bowmanvillegolf.ca and winningwebsitecreations.com

Not sure what to do next. Would appreciate your help. Support Access is granted on both sites.

Thank you.
