Background Color on Blogs

What blue background color?

I don’t see blue on that site – it’s quite brown/grey. You can set it under Appearance > Background.

Does the blue background not show up for you? Here is an example: https://sideoftheroadsessions.com/this-too-shall-pass/

Did you clear your browser’s cache?

Blue in the content section, yes. But where are you making these changes? You should not be modifying any theme files — they will be overwritten when WP is updated. Rather use a Child Theme or custom CSS.

Yes, just cleared it and the blue background on my blogs still shows. Hmmm. I also tried opening by website/blog in another browser and it’s there as well. Strange!

I never intentionally made any changes to the theme files, so I have no idea how to undo this. It sounds like I just need to wait for another WP update?!
