Suddenly no longer receiving Admin email notifications.

I added module Ceon URI Mapping (SEO) to Zen-Cart 1.50

Since then I no longer get admin email notifications for orders. I still can get contact_us emails. Order confirmation emails are being sent to customers. If I turn off URI Mapping in admin config the problem still persists. I assume that when I added the URI module I made an error in a customized file edit somewhere when I couldn't simply transfer the whole file.

So, what file could I have edited that would only disable admin email notifications?

At this point I am just trying to narrow down what I need to look at.

Thanks for any help. Bruce J.

I can't imaging that CEON URI mapping would cause a problem with your emails even if you did make a mistake editing the files. All (as far as I know) the edits in the core files are just to include classes and files for CEON so it shouldn't do anything to the emails. If you are still convinced it's something you did when editing files why not just look through all the files you edited and winmerge them with original zen1.5 files and see if you've accidentally deleted something
