Hi
I know that this topic is a few months old, but i think it is better to continue the discussion here that creating a new topic.
At the moment I use another plugin for domain registration, but want to change it to WP24 Domain Check in the future.
As I mentioned above the strings can′t be translated with WPML and I can′t change to qtranslate or use both qtranslate and WPML, it creates conflicts. I have tried to follow this link, but unfortunately it did not work.
I have tested to translate your plugin with both wpml, loco translate and Polyang and none of them worked.
Have you seen that you can get a free WPML account as developer. Se this two links below.
https://wpml.org/purchase/theme-and-plugin-developers/
https://wpml.org/documentation/support/go-global-program/
If you would have time to look into this, that would be great. I think other users would also appreciate WPML support
