Help wanted for Categories Center Box Module by Numinix

I'm using the categories centerbox module by Numinix found here https://www.numinix.com/categories-center-box-module

This is relying on http://MYWEBSITE.com/index.php?main_page=index&cPath=0 to display the categories centerbox. However I cannot set up separate Meta Titles, Meta Descriptions and Meta Keywords for this page as effectively you cannot set these up for category 0 (zero) through the admin.

How would I do this?

Resolved this in the database by editing meta_tags_categories_description and setting up a row with category ID 0 (zero)

I am using a modified version of ZenCart 1.5.1
I am trying to get this to work on what is essentially a cloned site of my main store. The configuration for this template is hard-coded so I can't just go to my "My Configuration" menu option.
I went straight into phpmyadmin and modified the to configuration key's.

(I don't have catagories_id in range 1-5)

is this the correct configuration to get those categories to show up on my main page? Am I missing something?
