10 second hotfix – not a fix just ignores the problem…
In the qtranslate_wphacks.php change this
if(inst && ! inst.isHidden()) {
tinyMCE.triggerSave();
} else {
qtrans_save(vta.value);
}
to this
if(inst && ! inst.isHidden()) {
tinyMCE.triggerSave();
} else if(vta){
qtrans_save(vta.value);
} else {
return;
}
