I installed the imagemanager plugin and configured tinyMCE accordingly (at least this is what I suppose). But when I try to insert images I get a popup window containing non formatted text:


Simple example

This is the most simple form of integration.
[MCImageManager]
Relative URL example

This example will output the selected files as relative to the current document.
[MCImageManager]
Absolute URL with document_base_url option

This example will output the selected files as absolute URLs but with a different domain prefix.
[MCImageManager]
Absolute URL without host

This example will output the selected files as absolute URLs but without the protocol and host name parts.
[MCImageManager]


I assume there is a configuration error, but can hardly understand where.


Any help is welcome.
