I hope you can help. I'm setting up a basic redirect using the code below.

    $iphone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$android 
= strpos($_SERVER['HTTP_USER_AGENT'],"Android");
$palmpre 
= strpos($_SERVER['HTTP_USER_AGENT'],"webOS");
$berry 
= strpos($_SERVER['HTTP_USER_AGENT'],"BlackBerry");
$ipod 
= strpos($_SERVER['HTTP_USER_AGENT'],"iPod");


if ($iphone || $android || $palmpre || $ipod || $berry == true){
    header
('location: http://www.ignitiondrivingschool.mobi');
    
exit();
}

I've done this on other sites with no problem, however, when I redirect from dev.ignitiondrivinglessons.co.uk the styling goes small. Refresh the page in the phone and it resumes as normal.

Small Version straight from redirect

Normal view once you refresh the page

Any help would be wonderful.

Thanks Mark
