#260 there is an incorrect URL in doc/about

http://yoursite/index.php/doc/about This ^^ is the "about text" that comes with every installation of GNUSocial version 2 ("nightly"). It writes (your site) is a social network based on the Free Software GNU social tool. In that sentence, "Gnu social" is a hyperlink to https://git.gnu.io/gnu/gnu-social but that don't exist. I guess it should be a hyperlink to https://notabug.org/diogo/gnu-social/ and while you're at this, the same URL pops up in doc/contact. You'll want to fix it there too.
