This is the support thread for the PO Box Ban 1.4

We've made some much needed changes to the PO Box Ban 1.3 mod, and I've packed the module hoping it would be useful to someone else.

Basically the problem was clients couldn't add a PO box to their billing address because the mod would launch an error message, so we started having complaints. The module was supposed to block the PO boxes from being added to shipping, not billing, but that wasn't working, so we made it work the way it should. Now customers can add PO boxes as their billing address, while the system will launch an error if a PO box is added as a shipping address.

Another problem we were facing, because our store was already active when we installed this module, was that customers with existing PO box addresses in the database were able to checkout without the system launching any error. We were able to fix that issue and added an extra piece of code (thanks to a piece of code by DrByte) to the shipping module (ours is USPS but same code applies to any other module), so when a customer tries to checkout with a previously entered PO box address as a shipping address it will launch an error message, preventing checkout until a new address is entered.

I've already uploaded the addon, so it's a matter of time until it's approved. This module is supper simple to install. Only 2 new files and modification to 4 files.

Hope someone else can find it useful!
