Warning: file_get_contents() [function.file-get-contents]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /home/vuster/public_html/admin.php on line 1026

Warning: file_get_contents(http://www.daddyscripts.com/version.php) [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in /home/vuster/public_html/admin.php on line 1026

How to activate it?

Hey lusher,

Open the php.ini and search the line -> "allow_url_fopen = Off" and change this to allow_url_fopen = On

Restart Apache
