While creating a new order from whmcs admin area the price is not updating automatically in the Order Summary area.
The issue started today after upgrading whmcs to 7.5.
The system has PHP 7.2 and fulfilled all whmcs requirements according to website system requirements page and whmcs health test report.
It is generating the following error:
[03-Apr-2018 18:20:33 UTC] [WHMCS Application] ERROR: Error: Invalid string offset in /path/to/whmcs/admin/ordersadd.php:0 Stack trace: #0 {main} {"exception":"[object] (Error(code: 0): Invalid string offset at /path/to/whmcs/admin/ordersadd.php:0)"} []
