    My apologies… I should have said what I have already done.

    I have checked the ends of both wp-login.php and functions.php and neither have anything at the end after the }. I have also checked the lines mentioned, they are:

    functions.php:3839
    trigger_error( sprintf( __(‘%1$s is deprecated since version %2$s! Use %3$s instead.’), $function, $version, $replacement ) );

    wp-login.php on line 421
    header(‘Content-Type: ‘.get_bloginfo(‘html_type’).’; charset=’.get_bloginfo(‘charset’));

    wp-login.php on line 434
    setcookie( TEST_COOKIE, ‘WP Cookie check’, 0, COOKIEPATH, COOKIE_DOMAIN, $secure );

    Without any actual php coding experience, I don’t know if they are fine or not?

    I’ve also disabled all plugins and themes, and still no luck.

    help?

    Ok an update… I ended up removing a sidebar in the default theme, and the Modify Header warning in debug mode has gone. Still… doesn’t help with the issue that I can’t log into the site with anything other than the cPanel passthough.
