Login screen unavailable with FIR hosted in subdirectory

[p4tpr0]

I've installed FIR on an existing Apache server, the application seems to work fine (not fully tested), but the login screen fails to load because of a wrong redirection:

My install is available at /FIR, but the application redirect non-authenticated users to /login/?next=/FIR/ instead of /FIR/login/?next=/FIR/ :

`$ curl -qLI https://server/FIR 2>/dev/null| egrep '^HTTP|Location|^\s$'
HTTP/1.1 302 Found
Location: /login/?next=/FIR/

HTTP/1.1 404 Not Found

`

Loading https://server/FIR/login/?next=/FIR/ into the browser allows users to log in and use the application.

Same goes with the BL choice menu in the stats/quarterly/ page: if my install is hosted in /FIR changing BLs send the browser to https://server/stats/quarterly/BL instead of https://server/FIR/stats/quarterly/BL.
