Undefined variable: limitreached in on line 1483

When I access uddeIM as a registered user I get the following error message in the compose section:

Notice: Undefined variable: limitreached in /mysite/components/com_uddeim/uddeim.php on line 1483

I don't get this error when I'm logged into my super administrator account.

When I am not logged in, I get the following errors above the messaging panel:

Notice: Undefined variable: pathtosite in /mysite/components/com_uddeim/public.php on line 112

Notice: Undefined variable: pathtosite in /mysite/components/com_uddeim/public.php on line 127

I'm afraid that I don't have any other user accounts to test it on. I have CB set to not allow duplicate email addresses.

Are these bugs, or are they caused by one of my settings?

Sorry to be posting so much with problems!

Don't worry about these warnings:

Remove this line to fix bug No.1:
[code:1]$limitreached.= " "._UDDEIM_SHOWINBOXLIMIT_2." ".$config->maxarchive."«»).";[/code:1]

Bug 2 & 3 will not longer appear since the Public Frontend as it is implemented now is removed in uddeIM 1.6. Instead a new uddeIM premium plugin will be taken place of this (with quite the same functionality), which has these bugs already fixed.
