I had topic excerpts working as desired — that is, they observed
post_excerpt_maxlength in all cases. I first did this with a plugin (which worked), then learned about
SiteSetting.always_include_topic_excerpts = true, so switched to that. Still worked.
About two days ago, perhaps after applying 2.4.0.beta4, excerpts started truncating at 50 characters. Very mysterious.
I’ve tried flipping
SiteSetting.always_include_topic_excerpts and reinstalling the plugin, and changing the value of
post_excerpt_maxlength, but no change. Still stuck at 50 characters.
Anybody else seeing this? Dunno what else to try.
