We are using JIRA 6.3 and, after a restart and UPM update, we are getting the following error in the logs:
com.atlassian.upm.license.storage.lib.PluginLicenseStoragePluginUnresolvedException: java.lang.IllegalStateException: Unable to find PluginLicenseManager component. Is a licensing-aware UPM installed?
This is preventing the add ons from displaying in the system and other add ons do not work. Any ideas on how to resolve?
