If your server is receiving these errors in your PHP scripts it is because register_globals has been disabled.
register_globals is a security risk and had not been enabled in PHP by default as of version 4.2.0. This setting is also disabled in PHP5 and the rumor mill says that this option is not even going to be an option in PHP6.
Most of the servers already have this setting off however for some time we have kept older servers enabled with this option for older sites that rely on it.
If you recently found register_globals errors on your website it probably means the scripts are running have not been updated in a very long time. (PHP 4.2.0 came out in April 2002)
We suggest that you update your open source software to the latest version or patch your scripts accordingly if you wrote them yourself so that they do not require register_globals to be enabled.
If this is not immediately possible for you, please open a ticket at our helpdesk and we will deal with your situation on a case by case basis.
We will post patches to commonly used scripts as we see requests for them. These patches can generally be applied without updating the entire script, however, if you are getting these errors it is probably time to update your script as it is likely not the only security risk found in your script.
Please remember to keep your scripts up to date and running the latest versions to remain compliant with our Terms Of Service. Keeping the scripts up to date also limits your risk of site breakage when security patches like this are released or installed.
Most every software distribution these days has a low volume mailing list for release notifications. If you run open source scripts we strongly suggest that you subscribe to these update notification lists so that you always remain current.
Security updates like this help to increase overall uptime and reduce potential site damage due to hacked sites from known security holes.
We apologize in advance for any inconvenience caused by these security updates and please know that they are directly for the benefit of your site.
