Hello,
You can achieve this by going there yoursite/templates/jf_creativia/css and edit menu.css at
line 9 :
div.main_menu li a, div.main_menu li span.separator { cursor: pointer; display : block; padding: 7px 0 25px 23px; text-transform: lowercase; color : #6e6e6e; font-size:150%; text-decoration: none; }
replace with
div.main_menu li a, div.main_menu li span.separator { cursor: pointer; display : block; padding: 7px 0 25px 23px; text-transform: capitalize; color : #6e6e6e; font-size:150%; text-decoration: none; }
Concerning the article it was written without a capital first letter...
hope it helps
Regards
