ho questa risposta:

Failed to load resource: the server responded with a status of 404 (Not Found)
(index):1 Mixed Content: The page at 'https:...' was loaded over HTTPS, but requested an insecure stylesheet 'http:.../templates/jsn_one2_pro/css/font-awesome.css'. This request has been blocked; the content must be served over HTTPS.
jquery-migrate-3.0.0.min.js:2 JQMIGRATE: Migrate is installed, version 3.0.0

ti può aiutare?

dove controllo se mod headers è abilitato?

can you write in english?

this is error: Access to Font at 'https.... has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '.....' is therefore not allowed access.

Can you take a screenshot of the dev tools so I can have a look? What is the resource that cannot be found? (404)

If you can share the URL I can have a look myself.

I cannot post www

the site is byaldino with .com

https

The website makes lots of HTTP requests and loads quite slowly for me (Finland). It took something like 20+ seconds to load the home page alone. It also loads/tries to load some resources from both the www and the naked domain and also from a mix of http and https, which causes some errors.
As for the CORS issue, the proper headers must be set for byaldino.r.worldssl.net if I am not mistaken. Which domain was that .htaccess from?

now I check it

this is my .htaccess

Header set Access-Control-Allow-Origin "*"

<IfModule mod_headers.c>
<FilesMatch "\.(ico|jpe?g|png|gif|swf|css|gz)$">
Header set Cache-Control "max-age=2592000, public"
</FilesMatch>
<FilesMatch "\.(js)$">
Header set Cache-Control "max-age=2592000, private"
</FilesMatch>
<filesMatch "\.(html|htm)$">
Header set Cache-Control "max-age=7200, public"
</filesMatch>
<FilesMatch ".(pl|php|cgi|spl|scgi|fcgi)$">
Header unset Cache-Control
</FilesMatch>
</IfModule>

Added a rewrite to respond with a 200 SUCCESS on every OPTIONS request.

RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]

READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE!

The line 'Options +FollowSymLinks' may cause problems with some server configurations.

It is required for the use of mod_rewrite, but it may have already been set by your

server administrator in a way that disallows changing it in this .htaccess file.

If using it causes your site to produce an error, comment it out (add # to the

beginning of the line), reload your site in your browser and test your sef urls. If

they work, then it has been set by your server administrator and you do not need to

set it here.

No directory listings

<IfModule autoindex>
IndexIgnore *

Can be commented out if causes errors, see notes above.

Begin - Rewrite rules to block out some common exploits.

If you experience problems on your site then comment out the operations listed

below by adding a # to the beginning of the line.

This attempts to block the most common type of exploit attempts on Joomla!

Block any script trying to base64_encode data within the URL.

RewriteCond %{QUERY_STRING} base64_encode[^(]([^)])

Block any script that includes a <script> tag in URL.

RewriteCond %{QUERY_STRING} (<|%3C)([^s]s)+cript.(>|%3E) [NC,OR]

Block any script trying to set a PHP GLOBALS variable via URL.

RewriteCond %{QUERY_STRING} GLOBALS(=|[|%[0-9A-Z]{0,2})

Block any script trying to modify a _REQUEST variable via URL.

RewriteCond %{QUERY_STRING} _REQUEST(=|[|%[0-9A-Z]{0,2})

Return 403 Forbidden header and show the content of the root home page

RewriteRule .* index.php

End - Rewrite rules to block out some common exploits.

Begin - Custom redirects

If you need to redirect some pages, or set a canonical non-www to

www redirect (or vice versa), place that code here. Ensure those

redirects use the correct RewriteRule syntax and the [R=301,L] flags.

End - Custom redirects

Uncomment the following line if your webserver's URL

is not directly related to physical file paths.

Update Your Joomla! Directory (just / for root).

RewriteBase /

Begin - Joomla! core SEF Section.

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

If the requested path and file is not /index.php and the request

has not already been internally rewritten to the index.php script

RewriteCond %{REQUEST_URI} !^/index.php

and the requested path and file doesn't directly match a physical file

RewriteCond %{REQUEST_FILENAME} !-f

and the requested path and file doesn't directly match a physical folder

RewriteCond %{REQUEST_FILENAME} !-d

internally rewrite the request to the index.php script

RewriteRule .* index.php

End - Joomla! core SEF Section.

Is that the .htaccess for byaldino.r.worldssl.net?

Hold on, just realised you use the CDN for that domain. You should configure the headers in the CDN resource for this to work. Do you have access to these settings?

yes - I do

ok, I try - thanks for now
