[imp] DB Error: connect failed

[chatuporn rungcharoensrichai]

Dear All,

I use horde2.0, imp3.1 and mysql when I login to use webmail it said

*A fatal error has occurred:*

DB Error: connect failed

[line 102 of /horde/lib/Prefs/sql.php]

Details have been logged for the administrator.


The 102 Line is
            if (DB::isError($this->db) || DB::isWarning($this->db)) {
                Horde::fatal($this->db, __FILE__, __LINE__);
            }

How should I do for resolve this problem?

Regards,
Chatuporn R.
