So, awhile ago i used to be able to get to a page where i could delete certain messages
that players said in the Chat Box, but now i can't seem to find that page. So my question is
did that feature/ability get removed, or was it changed and i just can't seem to find it?

I thank you for any help you may be able to give me.

Hi there,

Thank you for your query.

Just go to admin panel > content > panel layout > Chatbox. There's a search icon, click on it and then "empty."

Hope this helps.
