The forum categories are minimized by deault so you have to hit the "+" icon to expand them to see them.

Hi,
Which are you using Bootstrap version (Bootstrap 3 or Bootstrap 4)? Please let us know your website url if it was lived. I can't view the template demo on the Rockettheme website.

Thank you very much. Please add below CSS rules to the custom.css file in the joomla template.

Don't forget clear cache of your website before reload your forum.

Beautiful. Thank you!
