hi,
just installed uddeim 1.1 and it seems to work properly except from getting the following php message...

Notice: Undefined property: cfirstwordsinbox in /var/www/vhosts/mysite.com/httpdocs/mysite/components/com_comprofiler/plugin/user/plug_pmsuddeiminbox/pms.showinbox.php on line 134

anyone knows what's the cause???

It seems that you are using a beta version of this plugin. Please install the plugin that is part of uddeIM 1.1 or better overwrite your file with the file from the hotfix 1.
