The form populates properly when I view entries, but upon submission it throws a WordPress error.

The same error occurs when trying to edit the form settings on the backend.

I have disabled all plugins except for GF. I applied a default WP template.

I am unable to downgrade to PHP 7.3 (Host no longer supports)

Hi Christopher,

Which PHP version are you currently using? Gravity Forms is compatible with PHP v8.2, so you can try PHP v7.4 or later.

Please enable the WordPress debug log. This will allow us to see if any PHP errors are being produced.

1. Edit `wp-config.php` and insert the following lines:

```auto
define( 'WP_DEBUG', true);
define( 'WP_DEBUG_LOG', true);
define( 'WP_DEBUG_DISPLAY', false);

```

1. Reproduce the issue.
2. Locate the debug log in: `/wp-content/debug.log` or the `error.log` file
3. Paste the latest lines here. No need to paste the entire log file. Just 20 lines or so will do. Please censor any sensitive information.

This was resolved via support ticket, the PHP ctype functions were not enabled.
