Should I upgrade to Divi 2.4?

The long answer: Starting with Divi 2.4, the Elegant Themes, brings a new way of working with your theme. Basically they introduce new features, which you only see in premium plugins like visual composer but the problem with those kind of plugins, is that sometimes they look much better in back-end then in front-end.

Add Favicon to your website in less then 20 seconds

A favicon (short for Favorite icon), also known as a shortcut icon, Web site icon, tab icon or bookmark icon, is a file containing one or more small icons, most commonly 16×16 pixels, associated with a particular Web site or Web page. A web designer can create such an icon and install it into a Web site (or Web page) by several means, and graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page’s favicon in the browser’s address bar (sometimes in the history as well) and next to the page’s name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page’s favicon next to the page’s title on the tab, and site-specific browsers use the favicon as a desktop icon.
