Checked my DeBug file and ...

what do these errors mean and how do I fix them?

Those are from February. Are there any from today? If not, delete them and don't worry about them. They probably happened when you were installing addons or customizations to your store.

Ok, I can do that. There is nothing at all from March showing up on there but I am having problems with the orders not showing up on the order section.
