Okay, that seems to have done the trick. I couldn’t figure child themes out (it kept saying the Template was missing) so I just added it to the regular stylesheet. Now I just have to avoid updating forever and I’m in the clear.
The child theme solution sounds like the simplest option for doofus like me. I’ll try that and let you know how it works. Thanks for the prompt response!
@red Deer Web Design, the sidebar tip works, thank you very much. The scrollbar issue stops the text from expanding into the new space created though: screenshot. As soon as I get that solved, everything will be perfect.
