Something weird is going on with the plugin Custom Sidebars Pro. I noticed that my categories do not appear on the side of my blog pages anymore and I have tried multiple things to get them to show again. The "Blog Sidebar" widget area has a red delete button on it - I have no idea why.
I have tried creating new widget areas, I have tried selecting just certain categories (which would be great if it was working!)
The plugin doesn't need updating. What's going on? Thanks for your help!
