By default, our web servers are configured with security in mind and have PHP register_globals disabled from within PHP.ini. This affects each entire server. But if you are using a third party scripts and are getting the error message shown below then you need to turn register_globals on:
register_globals is disabled in php.ini, please enable it!To do so, you need to add the following line into your .htaccess file:
php_value register_globals 1
This will turn your register_globals on and your script will work properly.
Perhaps you might ask why is register_globals disabled in the first place? Leaving
register_globals turned on poses a security risk for an entire web
server. It should therefore only be enabled on a case by case basis and only per website. Web developers on the other hand, are phasing out scripts
that require register_globals to be turned on.
