Goran theme, how to remove "posted on" and "leave a comment"

Hello,

I’m using the Goran theme, and I have been trying to remove the “the posted on” and the comments facility on my pages. So far I have succeeded in removing the dates of posts (but not the words “posted on”, which I would also like to remove) and I have disabled the comments form (when I click on “leave a comment”, the link does not lead anywhere) but I would also like to remove the words “leave a comment”.

I would be very grateful for any suggestions.

Thank you very much
