Prefixes doesn't seem to show for me in ipbs 4.1.9.2 beta. don't know because of the beta though. I'm using the default tag and prefix system and want to add a prefix from a tag so that it shows before the topic title.
I removed cache and disabled all other plugins and apps. the prefix is gone when I enable this app again. I also turned all tag settings on.
Just wanted to inform you if it is because of the beta.
