Getting "get" error when trying to open Orders fromt the WP front end

I am getting this error when trying to access WHMCS Orders from my home page

Warning: file_get_contents() [function.file-get-contents]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /home/lbshostc/public_html/wp-content/plugins/whmcs-wordpresss-integration/whmcs-integration.php on line 728

Warning: file_get_contents( [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in /home/lbshostc/public_html/wp-content/plugins/whmcs-wordpresss-integration/whmcs-integration.php on line 728

I saw something about changing WHMCS file but didn't do it when I first saw the message.

I have looked everywhere but cannot find this fix. If it was put on the usage page it would be much better as well.

Can someone point me to where I can find the message that tells what files to edit to fix the "put" and "get" issue?

Many thanks in advance.
