When you use the OP Builder to create blog posts, or posts on custom post types that have archive pages, the way WordPress works is to grab the first available text on the page to create a post excerpt automatically. This is how it works with most themes, but due to this normal WordPress behavior, if you include text such as the date, author, category, as well as headline element, then it may grab that text first. To remove those texts you’ll need to use a custom post excerpt.
If the theme you use has the ability to use custom post excerpts, such as what the OP Smart Theme does, then you can easily modify the post excerpts with 3 easy steps:
Step 1: When you are done editing your blog post with the OP Builder, closing the editor will bring you back to the default post edit screen where you see the blue “Edit with OptimizePress” button. Just click in the top right corner “Screen Options”
Step 2: Check the box for “Excerpt” which will add the “Excerpt” meta box below the post edit screen.
Step 3: Type in your custom excerpt. This will override the detault.
Here is a screenshot showing you all 3 steps:
Once you do this, click the blue “update” button to save your changes. After doing that, you may visit your blog index page or archive pages to see the custom post excerpt.
