Okay, thanks for your help!
Hi, Thanks for the response. So just to be clear, once I am aware of the differences between old Bootstrap and new Bootstrap, I would somehow have to add/change class names to the affected elements of the site with the use of PHP filters?
Or is there a different way to do it or am I completely wrong?
I’ve added the extra css and it fixed the problem.
Thank you very much!

Update #2: I have actually overlooked a setting in individual header settings which by default makes font weight bold.
Resolved.
Update: Some of the headings are even 700 font weight even though before adjusting the setting it was set to 500.
Great, Thanks for the response. So for now is there any CSS or php code I can use to make it light header across all pages? Because for example pages like the 404 error page I cannot edit that page manually in order to add light header and eventually future posts will be a pain to always have to change to light header.
