I have built a new website in Joomla 1.6. I found a component which is designed for Joomla 1.5. It cannot work. The error message is "Call to a member function getUserStateFromRequest() on a non-object". I did research. I found a related post in
Joomla Forum. That is because in Joomla 1.6, $mainframe is not existed anymore. The component I installed is tried to call getUserStateFromRequest() from $mainframe. Then the solution is simple.
Please add this in /administrator/index.php

Code

Now, that is all works now!

Wordpress group must be working so hard. Not longer ago, they released version 3.0. Today they released an upgarde, version 3.0.1! They are great!. In this release, there are some bug fixes.

Wordpress 3.0 is released. That is more like a real CMS now. You can set admin user name during the installation. Moreover, it has more options to customize your menu. Even you can create own your content type. Well, now Wordpress is not a blogging software, it also can be a CMS.

I have upgarded to 1.5.17. But I found the "Save" button for all edit views are not working. I got a javascript error:tinymce.get is not a function.
Then I found that seems to be a bug.
But Joomla got the patch.

All you need to replace the onSave function is in plugins/editors/tinymce.php
