Allow URL Include

In the newer versions of PHP, they have included a new directive to control and handle remote includes. We disable this option, by default, which may affect some of your PHP scripts.

How to enable Allow_url_include

In your php.ini, put the following line:
  allow_url_include = 1
This enables remote includes.

Note: This requires allow_url_fopen =1 as well, so you may want to search through your php.ini and make sure that is enabled. Also, you will need to copy your php.ini into the directory on your server where the script is which is calling this directory. For example, if you have a script in public_html/blog/ that needs this setting, then copy the php.ini into public_html/blog.
