I too am having a problem.
I am using WordPress 3.0.1 and TinyMCE Advanced Version 3.2.7
I have installed the plug in as I usually install plug in – in this case I uploaded the zipped version, and then installed and activated the plugin.
However, when I edit a post or a page, the basic WordPress editor shows up. I cannot therefore access the advanced features of TinyMCE Advanced
Any help, very much appreciated.
Regards,
Steve
