I suggest to ask qtranslate-x guys, they’ve active community there.
There is defenatily something missing in Key4ce osTicket Bridge because as I told you before all the other plugins works fine with multi-language support.
Made a small fix to get it to work with WPML
you can try and use the latest ost-bridge.php from the trunk see if that also fixes things for qtranslate.
I suggest to add Suggested templates to the localization scope and add some CSS for RTL admin:
Example:
.key4ce_pg1 {
text-align: right;
}
.key4ce_adostmenu li {
float: right;
}
