Advice needed! Second blog on jekyll in github pages

Need to create second blog on jekyll in main blog version.
first site:
but second does not see posts
tried different ways of denoting baseurl, now it directs to: baseurl /new

not real clear what you are trying to achieve. Did you make a new repo named new? are there 2 sites or 1? if it is one site and you want blog categories or something that is pretty easy.
