[Solved] language translation
If you can’t find some phrase you can add it using [Add new] button.
IMPORTANT: If you did some change in phrases, please don’t forget to delete phrase cache in Dashboard > Forums > Dashboard admin page.
First of all, please one by one press on the [Delete phrase caches] then [Delete all caches] button. If you have other cache plugins delete those plugins caches as well.
Finally, press CTRL+F5(twice) on the forum frontend.
If it doesn't help please try to translate it using Loco Translate plugin.
only for information: In the german translation file wpforo-de_DE.po is the translation for "subscription" wrong! The right word is Abonnement (not Abonement).
