Thanks John
Short answer, keep them both active
For the excerpts output some themes use the_content()
and some use the_excerpt()
The option allows you to allow or disallow our plugin to filter (modify) the output of those functions.
It doesn’t change how our plugin generates the excerpt, it just changes whether the plugin should do it or not.
Both the_content()
and the_excerpt()
functions are used by themes.
the_excerpt()
specifically outputs the excerpt of the post (either the manually applied one or it creates it from the post content)
the_content()
works a bit differently, on the singular page for the post it displays the full content, but on a page which lists posts (like homepage) it displays either the full content or an excerpt, depending on the settings. The tag <!--more-->
is used inside of content to determine the cut-off for the excerpt.
That’s not directly related to the plugin, it’s just the different ways WordPress can handle excerpts and it depends on the theme which approach is used.
If you have the checkbox for the_content()
disabled and the plugin is altering the excerpt then it means the theme uses the_excerpt()
function to output the excerpt.
