My forum font have suddenly become big? My font was same like MYBB community before but not it look ugly, how can i make my forum font like before?
I think the body, large font, and / or small font might fix that problem. Try looking around there in the Theme editor.
Alternatively please provide a link to your board because we have no idea how to fix such a problem without setting what went wrong/viewing the CSS for your theme.
