pages sidebar disappearing

[mvlcek]

I'm trying my hands on making a plugin, and I have encountered a problem already...
I added a side menu on the "Pages" tab, but when I click it, all I get is the output of the function but all the side menu's are gone(i.e.: "View all pages","Create new page" and "Activities")

Add 'pages' as 7th parameter of register_plugin:

Code:

register_plugin(
    $thisfile,    // ID of plugin, should be filename minus php
    'Activities',    // Title of plugin
    '',    // Version of plugin
    'Jeroen De Busser',    // Author of plugin
    '',    // Author URL
    '',    // Plugin Description
    'pages',    // Page type of plugin <== which tab to show when plugin is displayed
    'activities_show'    // Function that displays content
);
