I migrated MantisBT 1.2.19 from a Windows server 2003 to a Windows server 2012 R2.

Unfortunately, MantisBT does not work. I'm looking for help to get this version working again, then upgrade.

Thanks in advance for your help

Hello Thierry,

This is an English-speaking site, you should be posting in English. Lucky for you I speak French too ;-)

Most likely, the problem is caused by your new server running a recent version of PHP, where the legacy MySQL extension is no longer supported (i.e. >= 7.0), which has been replaced by MySQL improved extension (mysqli)

The fix should be as simple as changing your config_inc.php:

$g_db_type = 'mysqli';

This is not a bug or feature request for MantisBT (you are asking for help on how to configure the system). I am therefore resolving this issue as "no change required".

Please use the forums to get support on customizing and using MantisBT (refer to for links and further details).
