Hi:
I was pushing commits to git hub, and the font size changed for everything when using the Academic theme. The navigation bar was also moved to the left.
Any suggestion to fix this would be appreciated.
The site looks fine to me. Do the normal browser caching stuff, and if that fails, take screenshots and post them somewhere so we can see what you see. 
Hi:
I was able to fix it. I was using the R package blogdown, and built the directory, which compiled all the .Rmd files. For some reason, the created .html copies caused this problem. I deleted them and everything was fine.
