I'm having an issue with the "Mandatory invoicing address" on the CBSUBs Settings>Display>Invoices page. While testing, I can only get it to give you a mandatory invoice randomly, and now it seems, I can't even get it to do that anymore. I need to force an invoice due to a bug in CBSubs that does not properly pull the state and country information into the invoice (which I need for tax purposes).

So, here is what I've done to try and fix the problem:

Uninstalled all CBSubs plugins and re-install.

Uninstalled all CBSubs plugins, deleted the "jos_cbsubs_config" table from the database and re-installed.

Tried using different computers (and locations) and different web browsers on each computer (firefox and IE7).

Cleared out all browser cache and tried again.

Cleared out browser cache and Joomla cache (Tools>clear cache).

Switched between "no invoicing address, non-mandatory address and Mandatory invoicing address", while testing member signup after saving each setting, and maybe 1 out of every 10 times when I set it back to "mandatory invoicing address" does it actually work.

I have checked the database table, jos_cbsubs_config and verified that when set to "Mandatory invoicing address" that the value is "invoicing_address_query=2".

I have also had other people test and they are experiencing the same problem.

Yes, they are able to bypass the mandatory Invoicing address. The are presented with the "non-mandatory" page instead.

I explained in my original post how I was able to reproduce the issue. Don't the invoice XML's get deleted when CBSubs and all the plugins associated with it are also uninstalled?

Well, I found the issue. If I have "city" listed as showing on the invoice, then they can bypass it. If I leave the "City Field:" as "-- Select Field --" under CBsubs>Settings>Display>Invoices, then it forces the mandatory invoicing address. When I set that same field as "City", then you can bypass the mandatory address. I would assume that when you force a "mandatory" invoicing address, that it is mandatory no matter what, but it doesn't seem to behave like this. Now, if you could only get the State and Country imported into the invoicing fields from the registration form, I wouldn't have this issue (you've already submitted a bug request on that one on a different posting).
