Ticket not saved when adding a custom field

[Andras]

We have encoutered a serious issue in ET/ETP. When adding (or editing) a ticket (RSVP or WooCommerce-based), and adding a custom field (any type), the ticket is not saved when pressing the Save Ticket button.

When removing the custom field, or not adding custom fields at all, the ticket is saved correctly.

All our current and future tickets need to have custom fields, so this issue makes our web unusable.

We have previously added multiple tickets with custom fields without problems. We tested on different browsers (current Safari and Chrome), and on two different installations of the same web, and the issue remains. Also, all other plugins are deactivated, and the default Twenty-Sixteen theme was used during testing.

After deeper inspection of the issue, the problem seemed to be caused by ajax calls to the file /wp-admin/admin-ajax.php. When %-encoded characters are posted (international character, or [] used by custom fields), any Save call failed. When no %-encoded characters were sent, the calls were successful.

The problem was caused by security settings blocking calls to the file admin-ajax.php (in mod_security module). After excluding the file from security checks, the issue is resolved. You may contact your web hotel/provider to change these settings.
