Unable to delete alert contact – CSRF token error

Hi Observium Team,

We are experiencing an issue when attempting to delete an alert contact in the Observium web interface.

When clicking the delete button, the operation fails with the following error:

WARNING. Possible CSRF attack with EMPTY request token.

Steps to reproduce:

1. Log in to Observium using LDAP authentication.

1. Navigate to the alert contacts configuration.

1. Attempt to delete an existing contact.

1. The CSRF warning appears, and the contact is not deleted.
