I'd appreciate if you could be more specific: which theme do you use: DaVinci or DaVinci 2.0?
Please make sure you've updated the plugin (ver. 1.4.9) and the theme (ver. 0.14.0 for DaVinci and ver. 1.2.2 for DaVinci 2.0) to the latest version.
If the issue persists, please feel free to send me a pm with your WP access details so I can check what might be the issue.
