The fact that the WPUA site is made with Divi indicates a fundamental lack of WordPress knowledge and / or experience to me by the owner. It's great for building personal / family sites for those that have no desire to learn proper practices. It definitely has a place and market niche. However, no professional that is STILL using Divi should be teaching anyone anything IMO let getting paid to do it. Lol.

Divi is just not a professional grade product. For the moment, it's just the MS Frontpage of this era despite it's power. I pity anyone has succumbed to the siren song of either WPUA or Divi in recent years. Both have a lot of improvements to make before they should be consideration worthy of any fiscal consideration.
