It seems after a network hiccup between the database server, the UI components are misbehaving:
I have verified that all the content does indeed reside in system/database. I can preview content by explicitly hitting a preview URL. Also, I have verified that all resources exist on the system by using CSDT command "listcs" for "ALL_ASSETS".
Since all the site content/resources still exist, I am hoping that there is some simple way to restore the UI components. Where can I find the UI config files that will allow me to perform this restoration?
Can you try cleaning up the cache on disk first and see if it helps?
With incache, cache on disk is stored in diskStore path specified in the cs-cache.xml, ss-cache.xml, cas-cache.xml, and linked-cache.xml files.
By default the path is set to java.io.tmpdir/*cache directory.
Stop the server, clean up the diskStore, and restart to see if the issue persists.
