 * Hi @daviidck,
    Sorry for the inconvenience. The generated error does not refer
   to the plugin section and we can not be sure that it is triggered by our plugin.
   Still, we want to help you but we need to inspect this by ourselves. It is hard
   to predict the problem like this. Hope you are willing to share more information
   with us to solve this matter. You can also connect with us from [our site](https://www.pluginever.com/),
   we also have a live support section there. Thanks a lot.
