My b2evolution Version: 1.10.x
I would have searched for this, but I honestly don't know how to describe it. I'll try though.
I was adding some of my content back into the sidebars using the widgets and somehow got a category list with checkboxes up in the header.. so I deleted all the new widgets that I had added, but it did not take me back to my starting point. The categories are still up there and I have no idea what I did to put them there or how to fix this.

I tried changing skins too and that didn't help.
I just upgraded to the latest b2evo software yesterday.
nevermind... I worked it out by deleting another widget.
thanks
