I upgraded to release 18.104.22.168 this morning, but on going to a release I get the message "Operation Unsuccessful
Do you use JIRA 5.0? Does 22.214.171.124 work?
I am able to reproduce this issue. It is related to a project version with no release date.
Taking down 126.96.36.199 from atlassian market place.
Should I downgrade?
Please downgrade. I will release a new version with fix soon.
This is resolved in 188.8.131.52
