Issue committing to github

[Lion666]

First of all, thanks for the nice theme you developed. I picked it up for developing my website :)

I used it locally using R blogdown & Hugo and it works fine.
However when trying to commit to github using git I always fail to commit successfully the repositoy coder-portfolio to github. All I have in github instead of a repository for coder-portfolio is a strange icon (like a double folder icon) with no ability to click on the folder to see the individual files.
I then tried manually uploading the folder themes/coder-portfolio to github; I also got the message "Committing the files to the repository failed." when trying to commit in the themes folder. I suspect it failed because the "double folder icon" folder because I can commit successfully in other folders..

Do you have any feedback of users experiencing issues committing the folder coder-portfolio to github? Any piece of advice on how to handle it?
