    Why is the Lightbox popup too small on my website?

    Asked by Hgna on October 04, 2016 at 06:24 PM


    my lightbox subscribe form is not working on any devices. It's getting cropped with scroll bars on the side and bottom.

    will it ever become responsive - and why won't it display properly neither on pc, nor ipad/mobile?

    please advise what to do.

    Hello Hans, the lightbox popup on your website was too small because of this:

    To fix this, just get your Lightbox Embed codes once again and feel free to customize the height and width of the lightbox modal upon your discretion:

    Afterwards, remove the codes you placed on your homepage and replace them with the new one.
