In order to activate Beaver Builder and start building layouts, visit any of your pages in the Pages section. Within each page, just click the Page Builder tab to launch the front end Page Builder!
After you click the Page Builder link, the page will refresh and if it is your first time opening the Page Builder you will have a pop up asking if you want to take a tour. Click No Thanks or Yes Please as you wish.
If you have existing content in the WordPress Editor, this will be pulled through into the Page Builder and remain editable.
Items from the menu can be dragged in and positioned in your page content. When finished editing, click the Done button and select to Publish your changes.
