UPDATE:
1. I talked to the webhost and they found a debug mode was on.
I do not know if any of the errors are still valid.
What do I do about the deprecated error on Master Slider?
2. Things seem to be working.
How do I enable the descriptions on the category pages and related products on the product page?
3. I am seeing things displayed improperly on product pages:

Thank you.
