wrapper is disabled in the server configuration by allow_url_fopen=0 in
Eventually you will see the following error somehow, somewhere at sometime.
This means that you have disabled ( or already was ) the following option in your php.ini: allow_url_fopen. This directive has been set to Off. This option enables the URL-aware fopen wrappers that enable accessing URL object like files. So obviously you have to turn it on. Go to your php.ini and find “allow_url_fopen”, then set this to On.
Now, save your file and restart apache.
