When logging into my impresspages as admin and clicking on menu management, I got the error:

"There are no languages. Please insert at least one language" lin 49 of ip_cms/modules/standard/menu_management/edit_menu_tree.php

I'm using php 5.3.1 with IP 1.0.2 beta. I've isolated this to be caused by improper construct of EditMenuTree. In this construct it will initialize the languages which the function manageMenu will need. However it sometimes does not construct properly.

I found out that the proper way of constructions in PHP5 are by using __construct(). I've renamed function EditMenuTree() into __construct() and now it properly initiates the class.

Does it happened on fresh installation? What should I do to get the same error message?

It was a total new installation on php 5.3.1 with the IP 1.0.2 beta, no extra's done at all. Except that I did do the .htaccess trick which I posted earlier 'install in subfolder'. viewtopic.php?f=7&t=68&p=254#p254

I thought I did first check if it was related to this and as far as I remember it didn't. So maybe it's related to php 5.3.1? It looks like it only initiaties the first time a session is started and not after. But I'm really not sure as it felt intermittend!

Let me know if you want me to test something
