Real-Time Find and Replace conflict with Social Warfare

It’s possible there’s a conflict, but past reports of conflicts were actually reports of a rule that is replacing something that wasn’t expected. For instance, a replacement rule for a word may end up replacing a path to an image file that contains that word.

To confirm your suspicions, you could remove all of the replacement rules you have and leave the plugin active. Without rules, the plugin doesn’t do anything so my expectation is that the Linkedin button will return.
