I can't translate the term "topics and posts" using Loco Translate. Both WpForo and Loco Translate are updated.
Thank you for a great plugin!
With best regards,
Please try to translate the phrase in wpForo phrase system. Navigate to Dashboard > Forums > Phrases admin page, find and translate the "topics and posts" phrase.
IMPORTANT: If you did some change in phrases, please don’t forget to delete phrase cache in Dashboard > Forums > Dashboard admin page.
