What I found was that I had added a cache plugin. Removing it did not remove the changes it had made to .htaccess. After I removed those changes, I was able to change fonts.

If you are still having this issue, I would suggest opening a new discussion, since this one is closed.

I will then mark this closed, and keep working it on my own end. Perhaps it is something in my own setup causing it, and I just need to track it down. Thank you very much for your time. I do appreciate it.

You are seeing the actual website, using wordpress 3.8. That is not using the beta2 code, because it is not a development site. The beta2 site uses the same child theme, though. Here is a screenshot of that development website:

Since I made no changes other than upgrading to the nightly beta2 code, my childtheme has not been changed.

Theme is twenty fourteen with my own child theme. I changed the fonts in style.css to font-family: Liberation, sans-serif;

That should produce sans-serif fonts, not serif. The fonts in sidebar, menu, headers, footer, and posts have all changed to serif fonts. firebug does not show any unusual changes to css, it tells me the font is sans-serif. The fonts in admin have not changed, and are sans-serif. My websites all use the same fonts, and work well, as seen in https://books.keepingdreams.com .

Sorry, have to get used to giving complete information again. The front-end, I believe it is. The part of the website that users would normally see.

And, if I recall correctly, probably not the right forum for this issue?

Adding a bit of information, the theme is twenty fourteen with my own child theme. I use this theme on my live sites, and it works great.
