Can't link to an Article

I'm trying to link only one article in my joomla, but after install JooDB I can't do it.
No shows it but always the same page where joodbd search catalog was made the main place to access the site.
Even now can't regret to another article/menu item the main entry place when you enter the site.

Do you know how to solve this?

Thank you!

I am not sure what you mean!
Please give a example. Article = Joomla Article or Joodb Entry?

If you want to link to a single entry take the catalog url and add the ID
Like this: Candy
joodb.feenders.de/db-example/6-candy.html
Or
joodb.feenders.de/db-example/article/6-candy.html

This is equivalent to
joodb.feenders.de/index.php?option=com_j...ticle&joobase=1&id=6

Sorry for not explain well. Let's try again...

All I want to link is a regular Joomla Content single article, not a jooDB item, in the Main Menu.
When I generate the new menu entry linking to "unique article" option all goes right, but in frontend when you click that item the site simply reload, not goes to the url's link.

The site is very simple, almost as a clean Joomla just deployed.
