hi all i want to set not mandatory the title field when submiting feedback
i can not find the line in the  form_feedback_add.php or in the form_item_required.php
any help whit this thank you.

@Nagy
It should be required if you see that * next to label. Make sure you have no javascript errors on your site.
But I would be looking for that in file:
oc-content/plugins/backoffice_manager/form/form_feedback_add.php
