I just installed Sydney Theme in wordpress and created a child theme. Everything went well but when I try to customise the theme features, I get an error “The requested URL /wp-admin/customize.php was not found on this server.”. Multi site is active in my wordpress. Can anybody help to fix this. I already tried the solutions recommended here but it did not solve the issue. https://doubtsolver.com/wp-login-php-was-not-found/
Thanks in advance.
