Dark UI issue in Discussion forum

Hello, I have recently started to learn & use gromacs and this forum will probably be helpful. I would like to inform the staff of this forum that whenever I enter the discussion forum (or any topic under that category) the website UI is shown as white and the text is pale gray, which is very hard to read, though I can use the dark UI in other fields, i.e. “Third party tools and files” and this “site feedback” categories. I also include the screenshots which would help to clarify the issue. I hope that you would solve the problem soon.

Thank you. Can you tell us on which type of device it occurs and which browser are you using?

I use Windows 11 PC and Firefox 94.0.2. I also would like to inform you that I cleared the cookies & site data but the problem persists.
