Today, i would like to share how to add the forum topic view count on the forum topic listing page.
1. Enable the core Statistics module.
2. Configure the Statistics module @admin/config/system/statistics. Enable the Count content views option.
3. Go to the forum topic listing page and the view count should be working now.
