I've installed Airtime 2.5.2.1 (manually, because none of the easy or automated installation worked) on Debian 8.0 x86_64.
The installation seems to be fine, but I can't login as admin. I've checked this post, but it doesn't fix anything.
I've checked /var/log/postgresql/postgresql-9.4-main.log which returns the following :
CET [] airtime@airtime ERROR: permission denied for relation cc_subjs
CET [] airtime@airtime STATEMENT: SELECT "cc_subjs".*, (CASE WHEN "pass" = MD5('admin') THEN 1 ELSE 0 END) AS "zend_auth_credential_match" FROM "cc_subjs" WHERE ("login" = 'admin')
