WebEnabled requires a browser feature called JavaScript. All modern browsers support JavaScript. You probably just need to change a setting in order to turn it on.
Please see: How to enable JavaScript in your browser.
If you use ad-blocking software, it may require you to allow JavaScript from webenabled.com.
Once you've enabled JavaScript you can try loading this page again.
Thank you.
Add the following setting to ~/.php/php.ini
allow_url_fopen = On;
This will fix the above mentioned error. This setting is disabled by default to enhance security.
