Remember that there are two register.tpl .
1. modules\profile\language\english\mail_template and in
2. language\english\mail_template

Make sure you changed in both places.

Hi there:
I am getting the same error ("There was an error. Your ad has not been added. Array") on any insert. On a PHP debug, saw the following errors:
--------------

I have put fixcatads but nothing seems to change. BT I am using XOOPS 2.0.11. Thanks in advance for any insight.
