With this plugin active, meta values don't save

Hi,

i noticed, that there must be a problem or conflict not in MB Term Meta, but maybe in other adddon together with main plugin (meta-box). I'm using a MB Group too - if i deactivated this, problem is done. Have you an idea, where the problem would be?

I solved this problem - MB Group addon was not uptodate, so i tried to install latest version and now it seems it works fine .. :/
