After upgrading, Confluence fails to start with a License iconsistency error. When trying to load the page to enter the license, a system error occurs.
The path displayed under Cause , i.e. '/template/simple/textarea.vm' does not exist - textarea.vm is located in '/template/aui'.
Steos under https://jira.atlassian.com/browse/CONFSERVER-52749 (deleting plugin directories) were taken, but had no effect.
Any suggestions are appreciated.
