I'm getting the following error message. This is a new install.

Notice: Undefined index: onInbox in C<span>:</span><span>\</span>wamp\www\cms\plugins\system\uddeim_hooks\uddeim_hooks.php on line 29

I'm using WampServer 2.5 (for testing) on a local computer. It is using Apache 2.4.9, PHP 5.5.20, MySQL 5.5.40

Any help would be appreciated.

Thanks...

Since there is no software available that uses hooks, deinstall plug_uddeim_hooks. That should fix your problem.

If you need hooks, you could try following:

In \plugins\system\uddeim_hooks\uddeim_hooks.php
add following line

if (array_key_exists($event, $this->callbacks))

right before

if (count($this->callbacks["$event"])) {


Btw it is only a "notice" not a warning or error, so no problem at all.
