This button was added from JContentPlus1.5. In JContentPlus1.5, hierarchical management of the category is adopted and, up to now, an efficient different method has been adopted. Therefore, when the category is made in the category management of Joomla, it is not reflected in JContentPlus1.5. Please push, and rebuild this “Rebuild” button when you make the category in the category management of Joomla.
It is not necessary to rebuild when made in the category management of JC15. Moreover, it is rebuild with the automatic operation at the installation.
