Forbidden to switch to old search page

For some reason, today I'm getting a “Forbidden” notice when I click on the “Switch back to the old search page.” link. If this continues it will greatly decrease my ability to do my hymnological work.  Why am I barred from it? And if it's a general thing, where the “old search page”, which I find MUCH more useful than the new, screen-space-devouring one, could you at least get them to remove that link to the good old days so I'm not irritated by it every time I look at a hymn? My apologies if I'm coming across as cranky. I am!
