Auto-generated excerpts are a different story though. Because they’re auto-generated from the post content, WordPress will call the the_content filter hook, which is what is used to block the full content.
Thanks, Justin. These would be auto-generated. I tried changing the code you posted to get_the_content and the_content and that didn’t work. I planned on wrapping the code in an !is_singular() check so that this only runs on archive templates. Any suggestions?
