Hi

I installed mantisbt on our support server and all the requests are made from outside (internet), so I configured two apache, one for the production server and one for the support server.

This is the conf of production server:
ProxyPass / http://192.168.0.53:5080/
ProxyPassReverse / http://192.168.0.53:5080/

This is the conf of support server:
<VirtualHost *:5080>

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/mantisbt/

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    <Directory "/">
            AllowOverride FileInfo
    </Directory>

</VirtualHost>

The returned error in browser is:
Refused to load the stylesheet '<URL>' because it violates the following Content Security Policy directive: "style-src 'self' 'unsafe-inline'".

Thanks
