Mysterious horizontal line

[scarabus (Wayne Dickson)]

I’m an “advanced intermediate” in respect to computers generally, a newby to RW, and a clueless buffoon when it comes to the most common web-coding languages used today. My relevant software is this:

OS X 10.11.6
RW 7.04
Theme: NimbleHost Glide 3.1.2
Stacks 4.x

A horizontal line @50-100 px or so appears to the right of the three-column stack I’m using — but only in Preview mode or after publication. I can’t see it in Edit mode. I don’t know enough to decipher the underlying code.

Any idea why this mystery line shows up — or, more to the point, how I can get rid of it. If I can, I’ll include a screen capture.

Thanks!

It llooks like the top of the sidebar. Usually there is a setting of the theme to show it left or right or to hide it.
Hiding the sidebar could solve your mystery.

You’ve definitely led me to the culprit (“sidebar header underline”), and to the remedy as well. Many thanks!
