Is not enough to hide author's name into parameters of the specific content item, but to do the same to the menu item which makes this content item to be displayed.This you did will not display author's name only when you click the title link of the specific content item. If you want to understand it better, go to Main Global Configuration -> Content and set Link Titles to Yes. By this way each title of each content item will be a link to each content item.

Amigamerlin no one is forced to help. We provide volunteer support here. Please be more gentle next time.I am working on Elxis Nautilus the last 2 months, I am focused there. I dont remember all Elxis 2009.x settings. In fact I never liked the parameters system as it is now. This is one of the things that is going to change in the future versions. To answer a question sometimes I need to go to see the code and this can not be done all the time as I work on other things.Thanks nikos for your help.
