UDDEIM 3.3 and Joomla 3.3 - error

I fixed the problem by uninstalling all component/module/plugin instances of uddeim (including the Kunena plugin which I'm not sure if will create another problem down the road) and then reinstalled. Everything ok so far.

I've done the same. The component and CB pligins work fine, but as soon as i publish the notifier module, any page in't published on breaks with the same error and kunena does the same when the kunena plugin is enabled

I am having the same problem after upgrading to Joomla! 3.3.0. I disabled the UDDEIM component and upgraded it to UDDEIM 3.4, and then enabled it. The error still appeared.

Please check if you have updated _all_ uddeIM components:
com_uddeim
mod_uddeim
mod_uddeim_mailbox
mod_uddeim_statistics
plug_uddeim_contentlink
plug_uddeim_hooks
plug_uddeim_searchbot
cb_plug_pms_uddeim
cb_plug_pms_uddeim_blocking
cb_plug_pms_uddeim_inbox
cb_plug_pms_uddeim_profilelink

When only one of these has not been updated you will get a conflict while loading the libraries.

Please check if Kunena uses a copy(!) of uddeIM API (or even worse, loads the libraries itself). When it uses a copy of uddeim.api.php so overwrite the file with the newer one from the uddeIM package.

Hello,

Kunena doesn't use a copy of uddeIM API but loads uddeim.api.php. Why it's worse for a component to loads the Uddeim library by itself ?

I am not talking about uddeim.api.php that should be loaded from uddeIM's component folder, but it should never ever use a copy of this file in its own directory.
