Hi all,
Having installed Roundcube for numerous clients, came across the first problem I have had installing it & got the very common 'Service Unavailable - Error No. 1f4)' message.
The install worked fine if the root mysql user was used as the roundcube database user, but not for the roundcube user which had been set up for the purpose, except for being able to access the first login screen.
After trawling the forums & not finding a solution, I began experimenting & found that setting in db.inc.php changing this line:
$rcmail_config['db_persistent'] = TRUE;
to read:
$rcmail_config['db_persistent'] = FALSE;
got everything working - hope this is useful for someone in future. MySQL 5.x was the db, in case you're looking for some solutiions when everything else doesn't. Bye for now, Terry
