I know this is a plugin and I have posted on their forums, but they are a very quiet place. So I am going to attempt to get an answer here.
In the Plugin control panel I can remove the category without issue. The problem is on my live site. The category exists and has random products within it.
The following is two links:
1. This is a screenshot of the admin control panel. You will see that the categories end at “j” (highlighted in red).
2. This is a link to our live site where you will see under the category “I. Coffees” there is a subcategory “k. Holiday Coffees”. I have removed this from the admin section, but it still exists live.
Thank you for any help that you may have to offer.
