On my Versions and Licenses page in JIRA, under JIRA Software I have a yellow message
JIRA Software is licensed but not currently installed
When I click the install button it gets almost all the way through until the end where a red box pops up saying "An unexpected error has occured check the logs for more information"
The only applicable thing I can see in the logs is a couple entries of this line:
2016-09-02 20:12:54,750 ClusterMessageHandlerServiceThread:thread-1 INFO [c.a.plugin.loaders.ScanningPluginLoader] No plugins found to be installed
I've tried clearing the plugin cache, but not sure what else to do.
