The plugin includes .po/.pot translation files. I recommend using Loco translate and settings the text domain and filename-prefix to “fslm.”
- Go to the page Loco Translate > Plugins.
- Click on FS License Manager.
- Click on Advanced.
- Set the “File prefix” as “fslm”.
- Set the “Text domain” as “fslm”.
- Save.
- Click on “Overview”.
- Click on “New language”.
- Select your language.
- Click on “Start Translating”.
- Translate the text.
- Save.
