I'm fairly new to WordPress, and just finished switching over the blog portion of my website. Everything was working fine until today when I started adding new sidebar widgets. Any time I have an active widget in the sidebar ("secondary area") the post width increases, such that the sidebar covers some of the text. If I remove the widget, the sidebar disappears as it's supposed to, and the text (oddly), shrinks in width to where it should be when the sidebar is active.
I left one widget in the sidebar, to show what I mean by overlap.
I've combed through all sorts of resources, but have had no luck.
Any help for a noob?
