How can you explain it works perfectly with 3.7.2 ?
Moreover, some things don't work with multi-sites while they work with 3.7.2
Example:
Once my multi-site are set up, I was not able, as admin of a site, to set the debug mode for the frontend. And many thing like that which work fine with 3.7.2
I keep my 3.7.2 ;-)
