Thank you very much for your suggestions, I ll try and post back with the results.
However, you mention my website does not have p tags. Actually the only thing I did about content was to include the sample data during installation process from JA Simpli template package and touch the Menu options in Category Blog changing the Blog Layout from 2 columns to 4 and showing 16 intro articles instead of 4 (I just copied some existing articles). That's why it looks like your demo (Explore>Layouts>Category Blog)
The only reason that I can imagine it does not already have the p tags is either because I have downloaded an older JA Simpli demo package or you have a different version than what you provide for wider use.
Thank you for your efforts, I ll post back with my findings.
