My Wordpress is crashing/resetting automatically. Why? Because of Free Account?

My website: https://nlclass.000webhostapp.com
My 000webhostAPP name is: nlclass

Situation:

  1. I installed TheGem template

  2. I imported ‘agency bright’ demo

  3. I was modifying ‘home’ page:

  4. and then suddenly Wordpress crashed and resetted. Error: https://i.imgur.com/O3ENMjR.png

What I’ve tried:

  • I’ve tried 5x times installing Wordpress again after crashing, I can’t figure out how to solve it.
  • I use a free hosting/domain with very little resources: https://i.imgur.com/hRvXbFX.png
  • Will the problem automatically be solved if I upgrade to a paid hosting? Or won’t that solve the problem?
  • I use the legal TheGem Wordpress template and I activated the code as well
  • I did not install my own scripts, queries, databases, users. Only TheGem template.
  • I did not play with ftp, SSL or site URL

Question:
How to solve it? Should it completely solve my problem, if I upgrade my free 000webhost host to premium hosting?
