Hi!
After the installation, changes the settings under “Configuration”. However, after pressing either the buttons “save and close” or “Apply” I get “Please wait…” and nothing happens.
The log file says:
[2016-04-12 21:10:44] mautic.WARNING: Command `doctrine:migrations:version` exited with status code 255 [] []
[2016-04-12 21:10:44] mautic.ERROR: PDOException: SQLSTATE[HY000] [2002] No such file or directory (uncaught exception) at /home\_pr4/v/i/visualcontext.net/htdocs/mautic/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php line 40 while running console command `doctrine:migrations:version` [] []
But I think the database is connected, because I could save a new landing page.
Thank you for any hints and advise!
