Your site doesn’t include support for the “co-blocks/media-card” block

    We are setting up our site using the Janice theme but since yester (Oct. 31 2019) the theme layout has disappeared from site. The theme is installed and active (we have tried to activate another theme, then re-activating Janice) with no change. When editing a page, there is an error message saying:

    “Your site doesn’t include support for the “co-blocks/media-card” block. You can leave this block intact, convert its content to a custom HTML block, or remove it entirely.”

    The content (of the media-card block) is displayed on the published site in standard WP layout and restoring a backup does not help.

    Please advice.

    The blog I need help with is

    Akismet Anti-Spam

    Theme Author

    Hello there,
    thank you for writing and using our theme.

    It seems that this block is managed or was created by the following plugin:
    Page Builder Gutenberg Blocks – CoBlocks

    So if you want to use it, you need to install this plugin in order to get the styles and functionalities. The theme does not add styles and support for any external Gutenberg plugins.

    Hope this helps,
    RIcardo P. from SiloCreativo
