Other Github pages were working before, but after I published my portfolio site at "username.github.io", they other sites appears to have turned into a pages of the portfolio site. To clarify: before, I used to host separate websites on "username.github.io/", "username.github.io/", etc. After I put up my main site at "username.github.io", the other websites "username.github.io/", "username.github.io/" etc have turned into pages of the site "username.github.io". "username.github.io" works fine when I visit, but other websites "username.github.io//" appear the same as "username.github.io" but with no data on them.
I read on this reply that the main branch
is where we put up files for "username.github.io". However, I have pushed my files to gh-pages
following the instructions at here. For more context all of the sites are react based.
