If you’re viewing a Static Block from the demo content and you see shortcodes in the editor you will need to activate or enable Visual Composer. Look at the top left edge of the editor to see if a blue button is just above the “Add Media” button with the label “Visual Composer“. If it is there, click it and use that to edit the shortcodes.
If you don’t have that button, go to “Settings > Visual Composer > General Settings” and enable the options in the “Content types” section for “page“, “post“, “portfolio” and “static_block” to make the editor active in that area.
I hope that helps. Let us know if you have any other issues, questions, comments, etc. Thanks!
