Steps to reproduce:
- Log into Zabbix
- Navigate to Configuration>Templates
- Choose template to edit
- Go into 'Items' screen
- Create 'Item' or modify current 'Item'
- Attempt to assign item to inventory field
- Save changes
Zabbix returns to a blank screen.
When viewing Web Inspector, it shows that there is an error with the `items.php` file when the request is submitted. Because of this, Zabbix returns a 500 internal server error. Screenshot is attached to this ticket that shows error
