Hi, after the MySQL problem, which I could fix, I have recompiled php to make a better availability to the server.
At this moment, everything is working perfectly, except sessions.
For some weird reason sessions are not stored.
session.save_path = "/var/lib/php/session"
I checked that, made user:group and permissions correct, I even gracefully restarted the server.
Logs tell me near nothing (except about 90k of rewrite logs)
I see nothing about php getting some errors. Nowhere...
