I have disabled the gzip compression in the Joomla administration and I have commented out all the “AddOutputFilterByType DEFLATE xxxx” instructions in the .htaccess.
Then I enabled again Cloudflare, but the problem is still there.
The “sytem - cache” plugin of joomla was already disabled.
Thank you for feedback in the meantime.
I am really sorry to hear that.
I cannot figure it out, however if this is something with Cloudflare, kindly I’d suggest you to write a ticket to the Cloudflare support and share your ticket number here with us so we could escalate your issue.
Old: Header set Cache-Control "no-cache, no-store, must-revalidate"
New Header set Cache-Control "no-cache, no-store, must-revalidate, no-transform"
Furthermore, just for safety, following this article: https://www.basezap.com/enable-gzip-compression-using-htaccess/ I have put the deflate directives in the .htaccess inside this “IF” control <IfModule mod_deflate.c>
