Q: Throw error External-format (:UTF-8) is not a property list

A: If you run the following commands in the REPL(e.g slime) whenever you're ready to regenerate your blog:

(ql:quickload :coleslaw) 
(coleslaw:main "/path/to/my/blog/")

and then, got the error External-format (:UTF-8) is not a property list.

I suspect you are running coleslaw straight from quicklisp. The next quicklisp release will fix things up or you can clone master and it should work fine.

You should do the following commands to install coleslaw from quicklisp local projects:

cd ~/quicklisp/local-projects/
git clone https://github.com/redline6561/coleslaw.git

and then run the coleslaw from REPL:

(ql:quickload "coleslaw") 
(coleslaw:main "/path/to/my/blog/")

Now, it should work fine!
