I had fairly heavily modified an existing theme to look the way I want in terms of colours, layout, etc.
Today, I wanted to try to change the sidebar to have a different sidebar on different pages but couldn't get it to work properly (note: I am NOT a programmer/coder, I do all this by trial and error, learning a little along the way). In going back to the default of the same sidebar appearing everywhere, I've managed to somehow get excess lines in between the sidebar list items. I've tried simply uploading the original sidebar.php file for the theme again but that didn't work.
How do I go about removing the excess lines?
