Subject: [PATCH] Update main_settings.php

Correct the below error by by changing line 98 to "'KEY' to 1 if $arrModuleIDs is empty, and if it's not empty, it will set 'KEY' to the maximum value in the array plus 1."

Message: Uncaught ValueError: max(): Argument #1 ($value) must contain at least one element in ...../plugins/dynamictemplate/admin/main_settings.php:98
