https://www.ejabberd.im/node/24776 en https://www.ejabberd.im/node/24776#comment-65272 <p>From your post on the mailing list, it seems you are using ejabberd 1.1.3.</p> <p>In that version, you do not configure modules with {mod_roster, [{db_type,odbc}]} to use odbc, so that will not work.</p> <p>Please refer to documentation provided with the version of ejabberd you are using.</p> <p>Regarding your error, the error undef, means the module is using a function call that does not exist. It looks like you have a problem with your installation. You may have missing modules or may be mixing modules development for different versions of ejabberd.</p> Fri, 27 Feb 2015 10:20:25 +0000 mremond comment 65272 at https://www.ejabberd.im
