Products won't show up to put in cart

Is there an issue with Homestead? My products won't show up in Preview, at times when they do, when I click on one, it brings up a blank white page. I sometimes get an Error message when I click on a product. It says, Oops....something went wrong.

When published, customers are having the same problem. This is not good for business. Is anyone else having issues like that? I seriously need this looked into in case there's something I can do to fix this, or if a Homestead tech needs to do on their end. I would really appreciate a solution to this problem.

I turned the store page off so nobody can see it online since it's not working.
