 > Hi @raskull, and thanks for the report! Unfortunately I cannot replicate
 this, I did what you described, but it correctly appends the `-2` suffix
 (also on multisite). Do you have any plugins active? Which version of
 WordPress are you using?

 Hi @flixos90, I just updated to 4.6.1 on a multisite install. Subfolders,
 not subdomains. No active plugins. Same problem: Create a post without a
 title. The auto-generated slug is /blog/1502 where 1502 is the post ID.
 There is no `-2` suffix appended.

 I can see this behavior only on the main site; the subsites do append the
 `-2`. The difference seems to the insertion of blog/ to the url on the
 main site.
