I'm having issue described here: github.com/w2c/ispconfig3_roundcube/issues/57 I can't post links here , sorry It's strange because my ISPconfig version is 3.1.2, I've checked both files, and they are patched but problem persists. Is there any way to fix this ? here is my error log from apache: [Mon Feb 20 12:49:00.587086 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/tform_base.inc.php on line 1185 [Mon Feb 20 12:49:00.587107 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/tform_base.inc.php on line 826 [Mon Feb 20 12:49:00.587109 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/tform_base.inc.php on line 1185 [Mon Feb 20 12:49:00.587112 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/validate_autoresponder.inc.php on line 55 [Mon Feb 20 12:49:00.587114 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/validate_autoresponder.inc.php on line 56 [Mon Feb 20 12:49:00.587123 2017] [fcgid:warn] [pid 10387] [client 127.0.0.1:55412] mod_fcgid: stderr: PHP Warning: date_parse_from_format() expects parameter 2 to be string, array given in /usr/local/ispconfig/interface/lib/classes/tform_base.inc.php on line 826
