If you are getting error messages when installing "Admin New Order", this means something was not installed correctly.

If the messages were about missing / unable to load language files, most likely one of the merges was missed (98% of the time is the cause). Another possibility is your Zen Cart "/admin/includes/configure.php" may have some invalid or strange settings (2% of the time this is the cause).

What exact page is that screen shot from? "/admin/invoices.php"? If so, something other than Edit Orders or Admin New Customer has modified the file (neither of these two plugins / modules touch the file). I repeat, neither of these modules make changes to "/admin/invoices.php".

That said, you should be able to copy over a clean version of "/admin/invoices.php" (download a clean copy of Zen Cart's distribution zip file and extract the original file). Keep in mind whatever other modifications have been made in your Zen Cart installation to "/admin/invoice.php" will be lost.
