The new installation of CIVI works. LAMP server, shared hosting, PHP 7.2, Joomla! 3.9, etc. When I click to go to configuration checklist, I get the error: undefined extension class 'Smarty_Internal_Method_Assign_By_Ref'
Same when trying to run the component.
Can't find an answer to this on Stack Exchange or general search.
Appreciate any suggestions.
