ownCloud has some default "apps" (something that would have been called "plugins" some years ago) installed, but working with emails is much more enjoyable using RoundCube.
I installed RoundCube using the SQLite option as database. This was the only one supported according to the installation check. However, at the end of the installation, something went wrong with the creation of the database file.
In the end, to get RoundCube functional, two "details" have to be taken care of:
- both
db.inc.phpandmain.inc.phpfiles need to belong the the web-server user (www). Achown www *.inc.phpis enough. - the path to the sqlite.db file should NOT include the 4 slashes after the colon like written in the example of the
db.inc.phpfile. 2 slashes instead would spare me the errors dues to missing database.
