My website has suffered a critical error and cannot be accessed via WP-admin. I don’t want to lose all of the user entries submitted to my Gravity Form ( but of course, I cannot access them via the Export Entries function in the dashboard).
Is there a way the historic data can be retrieved via FTP?
The FTP protocol is for transferring files and as the entries are stored not in any file, but in the database of your site, you would need to access them via mySQL. Reference Gravity Forms Database Structure for how the data is stored. Any file uploads associated with entries could be accessed via FTP. They are stored in the /wp-content/uploads/gravity_forms/ directory of the site.
