Powerpress Diagnostics – Recommended Settings?

I have looked for and so far can’t find a page with information on the recommended settings that are checked in the Diagnostic tool. In particular the Detecting Media Information.

Mine currently has a Warning

Your web server supports the PHP cURL library. Your web server is also configured with the php.ini setting ‘allow_url_fopen’ enabled, but the cURL library takes precedence.

Warning: The php.ini setting ‘open_basedir’ will prevent the cURL library from following redirects in URLs.

If you are still having problems detecting media information, check with your web hosting provider if there is a firewall blocking your server.

• allow_url_fopen: true
• curl: true
• curl_ssl: true
• openssl: true

What changes are recommended to remove the warning?

Thanks
