Today I installed the plugin "Advanced Excerpt" and noticed pretty quickly that it wasn't working. I fiddled with the options, tried using the the_advanced_excerpt() template tag, etc, but no luck. I tried two other excerpt plugins: Better Excerpt and DP Excerpt. Neither of those worked either.
At this point I began to suspect there was a conflict between those excerpt plugins and one of my other plugins, so I disabled all of my plugins except Advanced Excerpt and it worked perfectly. I began activating my other plugins one-at-a-time until I found the culprit, which turned out to be Crayon.
I've googled around for a solution, but come up empty handed. Anyone have any suggestions for getting these plugins to play nice?
