I'm still trying to make sure I understand what's happened. Here's what I think I understand...

[list=1]
[*] Installed Hotcakes Commerce 3.5.0 on DNN Platform 9.8.1
[*] Configured and used Hotcakes on a site.
[*] Created a new site on the same instance of DNN.
[*] Navigated directly to a newly created page.
[*] Added the Category Viewer module to that page.
[*] Viewed the page and only see an error displayed
[/list]

Does that sound correct? In general, it's useful to have "steps to reproduce" to help folks understand the problem. :)

Did you try deleting that page and clearing it from the recycle bin, and then running through the wizard instead? This may be a result of not having a store created for this site.

Hi Will,

The steps taken were:

1: Installed HCC 3.5.0 on DNN 9.8.1
2: Placed module on page.
3: Completed configuration wizard added example products and categories.
4: Navigated to Category Viewer page. The error was present at this point.
5: Attempted to setup a store on another pre-existing portal on the same instance of DNN to see if the same error occurred and it did.
6: Returned to the original site. Removed the page and cleared recycle bin. Setup the store using the wizard a second time. With the same result.

Also, all the modules have a similar error.
