Symptoms
After upgrading or installing JQL Booster Pack into your Jira instance, some filters have stopped working and are unusable.
Diagnosis
You are using JQL Booster Pack v1.2.0-RELEASE or higher, in conjunction with 'Script Runner for Jira' , 'JQL Tricks' or another app that also provides new built-in JQL functions.
Cause
Some other plugins may provide functions with the same name as those provided by JQL Booster Pack, e.g. subtasksOf() or parentsOf(). For functions like these, no other name would make a great deal of sense, so this is not surprising.
