Eclipse C/C++ thick white vertical line on the left

Question

I am using Eclipse IDE with C/C++ plugin. When editing C/C++ code, the editor shows this thick white vertical line on the left that i would like to turn off. I searched through plugin and general setting but i couldn't find the option to turn it off.

This figure shows the line that i wish to disable.

Answer 1

I think the problem is in the color theme you are using for the editor. Is the line present when you use other themes?

Answer 2

I was just trying to get rid of it and ended up here. I tried to right click on the line and select Folding->Enable Folding. Deselected that and the line is gone! Not sure on how to change it to a different colour though if you want Folding enabled.
