    Hi, please update to the newer Oxywind version.

    • ThatWebsiteIsMe says:

      The Oxywind plugin is at 1.0.3 with no update option and the plugin in the download dashboard is also 1.0.3.

    • ThatWebsiteIsMe says:

      Updated to 1.0.7 – plugin deactivated (plugin was renamed in update) and re-enabling it fixes the issues. Thank you.
