Foren / Cotonti / Support / minichat plugin broken after update :)

Hey

we have been runing the minichat plugin for a couple of years now up to version 6.1.7 it was working fine, after i have upgraded my cotonti to 6.2.5(step by step) it has broken

it works fine but once you write a message and click "shout" it disapears and only "all messages" is left.

any ideas? - yes we have updated the plugin too.
