Hello,
About “Page slider”, please read the description “Show revolution slider instead of breadcrumbs and page title”, but your Breadcrumbs is disabled, so the slider can’t be shown – https://prnt.sc/d3jEeKRrgG5Z Please check now – https://prnt.sc/sQd9J6KweXrt > https://prnt.sc/MLlGopmJS85n
About “Disable copyrights”, there is nothing to disable, because these areas https://prnt.sc/dCpddezjSXCp are already empty.
Regards
