    Hi there!

    Seems like here WP Contact Slider is conflicting with some other plugin. Can you share your theme and list of plugins at support[at]wpepxerts[dot]io so that we can try to dig and fix it for you.

    Thanks!

    Hi there!

    We were experimenting WordPress Contact slider with theme the7 and saw the above mentioned conflicts. And while digging for the fix here is what we found from the author of the Meta Box API which we both are using.

    Here you can view the comment of the Meta Box author

    According to him;

    The errors above come from the custom code of your theme dt-the7. They’re not in the code of the Meta Box. Please contact the theme author to make that code compatible with Meta Box.

    So you need to contact your theme author to update their meta box API to avoid these sort of conflicts with other plugins using the same Meta Box API.

    Let us know if still you have any thing we can help you with.

    Thanks!
