Can you tell me how I can view the post/page excerpt area?
This is not appearing as a screen option. There a times when the excerpt needs to be edited, for example with seo and others and the vc columns and shortcodes appear automatically.
im not quiet sure to understand your question, but please see this article: http://www.wpbeginner.com/plugins/how-to-customize-wordpress-excerpts-no-coding-required/
hope it helps,
