Thanks for your reply!
Host papa does an automatic backup every night it appears. I could try to restore it to the backup from a couple nights ago, but I’m worried I’ll just mess things up even more.
Also, when I go into PHPmyadmin, I can see all my content in there, my old posts and pages.. but I don’t know how to get all of that content back into WordPress.
I tried exporting the database from PHPmyadmin to both an XML and a CSV file, and import them using various importer plug-ins such as WP All Import, but I don’t think I’m doing it right. When I upload the XML file with WP All Import, it imports 3,348 ‘columns,’ 487 ‘tables,’ 12 “pma_tables”…. and I only had 3 blog posts and 5 or 6 pages on my site in total.
