Steps to reproduce:
- Get DB hash from tabels: report, report_param, report_user, report_usrgrp
- Go to zabbix.php?action=scheduledreport.list
- Choose any report and open it
- Do not make any changes and press Update
- Get DB hash again and compare them
Result: hashes do not match.
This might need to be repeated 10-20 times to reproduce the problem, easier to reproduce by using Selenium tests.
