 * Unfortunately, I can not replicate the issue.
 * Where does the error occur ( on which pages )? Do you have Meta Box plugin installed
   and activated on your site? If so, which version?
 * Could you please send a message to our support using contact us form [here](https://www.usabilitydynamics.com/contact-us/),
   so we would be able to troubleshoot your issue directly.
 * Regards.

 * Issue Resolved!
 * For those that may find this:
 * The direct cause of the issue is unknown but is possibly due to some customization
   on the site and/or the number of plugins installed on the site.
 * The developer made a change to the plugin that will prevent this issue in the
   future.
 * A+ Support! Thanks!

 * Hi,
    we’ve got the same problem here since a theme update. Our theme use metabox,
   so i think there’s a conflict. Is there a new version of the plugin ? Where could
   i desactivate metabox declaration in your plugin ? Thanks for help
