Auto Excerpt Length feature allows you to set the number of words for Memberium to use from the page/post’s content to automatically create an excerpt or teaser content.
You can find Auto Excerpt Length feature from Memberium -> Settings -> Content Protection screen. See the below screenshot…
The length of the teaser content is measured in words, not characters.
The default setting is 55 words. Memberium will use the first 55 words from the content to automatically create the excerpt/teaser content.
