Recently, I had an issue with JIRA Software. It was missing but I could not install new version. I solved it by upgrading JIRA to 7.5.0 version. Only after that, I managed to upgrade JIRA Software.
However, now I don't see "Boards" tab. What I found in the logs is:
JIRA Agile : com.pyxis.greenhopper.jira
Version : 7.5.0-DAILY20170902071651
Status : disabled
Vendor : Atlassian
Description : Agile Project Management for JIRA (Build: #1655ee4b64cb1a29)
Can you please give help to get back my "Boards" tab ?!
P.S: Why am I getting this "invalid html" error ?!!
