I want an immediate solution to this problem, please. Because of it all the time, my forum stops working completely. Yes, when I delete this record, my forum stops working permanently and a problem occurs in the Database.
if it is add on go into the control panel for your xenforo.
go to the add on tab.
find the add on.
click on the little gear with a down arrow to the other side of the add on name.
click on uninstall or disable.
if it is a style option then you can ask the person who created the style.
