Portfolio for JIRA v.3.x Enabling Capacity view caused a complete crash of the plan

[Karolina Durucskó]

Dear All,

I was really happy when I had realized, capacity view is now available in Portfolio for JIRA. 

https://confluence.atlassian.com/jiraportfolioserver/grouping-by-teams-967895212.html?_ga=2.145306423.2011764375.1595837673-583333466.1592897458 

I was following the instructions of this article from Atlassian Documentation, however, I have received  "Something wernt wrong" message. Also ever since then plan backlog runs to a blank page. 

What could have gone wrong? Has anyone met this issue before? 

Thank you for reading this, 

Karolina
