Hey @talbarashi2,
Thank you for reaching out! The translation files for both the core plugin and the pro plugin are included in the core plugin.
Please make sure to update SliceWP core to the latest version, as we’ve recently updated the translation files (in SliceWP version 1.1.18) to include the specific add-on you’ve mentioned.
Also, considering that you’re a customer, if you’re still having issues or have any questions about SliceWP, please open a ticket from your website, here: https://slicewp.com/contact/
Thank you and best wishes,
Mihai
