I received a response from the Impreza developers:
Hello, unfortunately, we have not declared support for this plugin, and it’s not planned. Impreza supports WPML and Polylang for creating multi-lingual sites.
Additionally, your plugin page states:
- Fully compatible with all themes and plugins.
That’s why I assumed that, in case of any compatibility issues, you would help resolve the problem. The plugin description is misleading
