When editing a single blog post, you will find the local options on the Post tab of the Avada Page Options. On that tab, are all the individual post settings that can be set for each Blog Post. These are local options, which can be configured on a post by post basis to override the global options, or left as is to accept the global defaults.
IMPORTANT NOTE: When using an Avada Layout for your Blog posts, only a few of the Page Options will remain active. These are Video Embed Code, Image Rollover Icons, Custom Link URL On Archives and Open Blog Links In New Window.
