I have tried everything...
I'm trying to initially configure 0.90 on CentOS 6.4 (x64). SQLite 3 is installed (I think this is OK, as although some of the notes indicate that only 2.8 is recommended, I read somewhere else that sqlite v3 db is now "required", so something's out of sync there, or I'm misunderstanding it, either way, I couldn't find a 2.x version for CentOS 6, and this is a really small install -- sqlite would be perfect versus running a "bigger" installation like mysql or postgresql).
Every time I get to the Test Config page in the "Installer", it fails on the DB Write, says the db is read-only. The db was initialized by running the sqlite init script (and indeed, I can login and see the tables it created manually). The sqlite.db file is chmod 777, the directory that it's in (/usr/share/roundcubemail) is also now chmod 777, all files are currently owned by root, group = apache (which is the user/group my httpd is running as).
I can't get past this setup step, and I don't see anything logged anywhere. Can someone please tell me how to troubleshoot further?
