You have added a redirect script to the page.

i dont know where it is sorry a newbie

do not redirect or redirect to a page in the site ?

Maybe you have used the following extension. If it is not in the page itself then it is possible you might have added via an .htacess on your server. Only you can remove this from the redirect.

i found it but how do i get rid of it in webbuilder ?

Found what the extension or the redirect in the .htacess file? If it is the extension you simply remove from the page you inserted it on you will then need to republish the page. If it is via the .htacess then you will need to contact your host/server provider as no help is offered on server configurations.
