[YF 7.0.4] Error when changing ticket status

[diderich]

When I try to save the ticket status, I get the following error:

E_WARNING: Trying to access array offset on int in /opt/crm7/app/Utils/ServiceContracts.php, line 399

Changing line 399 from
if ($row['working_days']) {
to
if (isset($row['working_days']) && $row['working_days']) {
addresses the issue. But that is probably not the root cause of the problem.

On the demo system, the error does not occur. So I assume I have an issue with the working days configuration, but have not been able to figure it out.

My business hours table looks like this:

Thanks for issue @diderich
FYI: $businessHours shouldn't be a multidimensional array here, so remove the foreach loop and replace $row with $businessHours and it should be OK ;)
