Okay, I don’t know how to explain this. I went to lunch, came back and started trying to set the colors on the categories and now all of a sudden I can set the color. I made ZERO changes between when I was trying it and now. It’s a complete @#$@#$ mystery to me as to why it’s working now.
BTW, not sure if it matters, but I did change the prefix; so, it’s not wp_. I changed the prefix many days before installing the plugin. None of my other plugins have an issue. Regardless, I thought I would mention it.
