Ariane,
Well since you selected “no” to the “Sample Content” then the Quickstart isn’t going to install it. Because it didn’t install it, there is nothing to see…meaning you need to build it yourself. In the Module Manager…click “New” and start building!
If you are new to Joomla…and especially since you are working with JA Teline III (one of the more difficult and advanced templates on the market) I would recommend STRONGLY you blow out everything you’ve done….and reinstall QUICKSTART with the Sample Content…and THEN either change what content you want to change, or delete whatever content you don’t want.
Have fun!
John.
