I have a website running WP connected to a MySql db, where the latter uses PHP. I did not make the site and have only small experience with WP. This may be a simple question. The WP also uses Elementor. I interact with the db via phpMyAdmin.
I have this page = http://linket.info/signup/ It accepts input data that does into the db.
See the labels ('First Name' etc). I can't seem to find them defined in WP. So they are in the db? I looked in the various db tables. But still can't seem to find these labels. Can you suggest what tables I might focus on?
