I bought a WordPress theme a few months ago. Until recent days, I just finished the basic layout style look (the most easiest way just rearrange the layout you know) based on the theme templates in Wordpress editor (my host is Bluehost). But during the phase, I have some really hard problems:
How do I make the navigation menu font larger? And become normal type to display but not capital letters (please see the image at: https://www.pinterest.com/pin/318629742389963348)?
My current WordPress preview URL is (not yet released) WordPress internal link, like this "http://box111111 (numbers).temp.domains/...", how do I change this to my official URL (www.xxx.com)? (Previously changed once but caused the preview pages can't open)
the sign up newsletter didn’t show, it said: “[contact-form-7 404 “Not Found”]”, not the normal look as the demo display, may I ask why this could happen? How can I adjust this? My newsletter service provider is MailChimp.
