Thank you very much for your help. Below I'll explain the solution so others can fix a similar issue.
Actually, in my case the uddeIM Notifier module is only installed *once* according to the "Extension Manager: Manage" list.
However, in "Module Manager: Modules" I by accident had assigned the uddeIM Notifier to two different module positions for the *same* menu items (in this case the Kunena menu), and *that* mistake triggered the error. So, the fix is to *avoid* duplicate menu assignment in the Module Manager.
Although it might not seem a bright idea to assign a module like the uddeIM Notifier to two different positions on the same page, this might actually come in handy for certain page layouts. Hence, I suggest that you consider to implement a sanity check that identify whether or not it's required to redeclare PHP functions
There is one additional issue: UddeIM registers an onload handler. It does not make sense to register this handler twice except you like to have two notifications.

Is there a way to avoid this even with 2 notifiers with 2 different settings installed? We are using 2 modules for users with different rights - but when moderators log on it messes up. A pity that simple double posting can be fatal here...
