Thumbnails not showing in featured and categories tab

Hello @mededleads !

Please set up your thumbs from Newspaper -> Theme panel -> Block settings -> Thumbs on modules/blocks: https://forum.tagdiv.com/theme-thumbs/. Note that if you deactivate a dimension from there, next time when you will upload an image, it will not be resized to that dimension.
After changing the thumbnail sizes you need to regenerate your thumbnails using a plugin. Check this guide: https://forum.tagdiv.com/using-the-theme-with-existing-content/

Thank you!
