Based on what I've seen as I've tried to clean up, I would need
Regex #3, however, when I add those search and replace terms I get:
Code:
Searching done: Replaced 0 occurrences of ([^>”\?\!\.])</p>\s+<p>
I made sure the mode was set to "Regex".
Regex 1 ran without a problem, and I didn't change anything in the code (I just copied/pasted).
