When trying to run the Cron job, end up with an error like this: "We're sorry, an error occurred. Try clearing the cache and code generation directories. By default, they are: var/cache, var/di, var/generation, and var/page_cache."
Would like someone who is skilled at Magento to not only fix the error, but let me know how to fix it.
It is likely I will hire the winning programmer again as I am sure I will run into other errors as I continue to build out my online shopping cart.
All the best, to your bidding success!
