I can type a blacklisted word in my public chat, UFilter will block it, i PM that same word, It is not blocked. i have Ufilter enabled in the config, saved and have reloaded the plugin. any assistance would be nice

Same here, and I get this error in the log. I made sure to have the latest version. In case you're wondering why I use ufilter over Better Chat Mute, it is because of things like if I censor the short word for the N word in BCF it censors the word "night" and stuff like that, since it is a phrase filter and doesn't have a function to add in more specific censoring in the case of a phrase also sharing non-offending words.
