Caused by disabled plugins in DB

Found solution from SmartTechPD post: 

1) Stop your JIRA

2) Connect to your database.

3)  SELECT * FROM pluginstate where pluginenabled = 'false';

4) UPDATE pluginstate SET pluginenabled='true' WHERE pluginkey='<pluginkey from query above>';

5) Start your JIRA
