Have an issue with a control that has been in use for a couple of years, which has been running fine on Ubuntu 16.04 and MySQL 5.6.
The control was developed with a field that had an event with an OnChange which runs a PHP script and populates some other fields. The hosting server has been updated to Ubuntu 18.04 and MySQL 5.8.
The control application is working but any change to the field seems not to be triggering the OnChange event and is thus not populating the fields.
Can anyone give me some pointers on how to possibly troubleshoot this issue?
Thanks in advance.
