I updated my website to the most recent version of WordPress (I have done similar updating several times in the past) but now find that something has apparently gone wrong. When accessing the website --> http://www.bettylocal.com <-- instead of the home page, it presents a new/different WP admin screen than I've seen before.
When inquiring with my host's support team, I am told the issue is that some of the tables are missing in the database. I am told that uploading the tables to the database will be required in order to fix the issue.
I do not now where to begin.
