@Jusanda. Thanks for posting. That’s a strange screenshot. Something like that typically happens due to some kind of error… typically a syntax error. What version of Joomla are you running? Is it the latest Joomla 1.5.26?
You should have a look at your PHP error logs, and post them here, or in an email to me, if you prefer.
Your screenshot should look like this screenshot of my site.
Once I get a look at your error logs, it should shed some light on what is going on. Have you tried to re-install the module?
