thanks, shandiz. could you help me access my ftp? i don’t know what that is? i’m a rookie at all this stuff:)

go to your cpanel or directadmin or other host panels , find file manager , go to public_html/wp-content/themes and your theme folder , then find functions.php and edit it.

thank you, shandiz! it worked… i’m very grateful! have a wonderful day:)
