Can you please add a hook that surrounds the payment_surcharge and tax display in the blocks/checkout/summary.tpl file.

If possible, please name it checkout:taxes_and_fees_summary

Or you can just use our EZ Hide Vendor Fields addon that can also modifiy email addresses in email headers and email company content.  The docs are located here.

Looks correct to me.  The only thing it could be is a permissions issue for that admin (if they're in an admin group, fix permissions).

Be happy to build you an addon that will track sales by vendor and collect the taxid/seller_type and then generate you a report (CSV) that lists total sales by vendor and their taxid for all or selected seller_type.

As far as your original post related to encryption, this too is possible with an addon to encrypt upon save and to decrypt upon get.   Be best to use a separate encryption key than the standard key hardwired into config.local.php.

Both of these could be created in the same addon.  Feel free to click the get-a-quote link in my signature and we can discuss your needs and I'll give you a quote.

That's not the URL of the button that is generating the popup.  Right-click the button and choose inspect and look at the 'href' value in the button.

If you have 3rd party addons installed, suggest you disable them and see if the problem continues.  If so, contact helpdesk.  If not, and things are okay, start re-enabling the addons one-by-one and test the results.  When it fails you'll have found the culprit.  Yes it's time consuming and it's the same process a developer will do to validate your environment. The more addons, the more time.
