Thanks Tim, Here is a bit more info...
I have also checked the installation with JSPUI enabled. Same issue. The Communities, Collections and E-Persons are all there, but none of the items added to collections. I have yet to re-force all the database indexing, etc, as yet. Perhaps before doing that, I will clear all my logs first and just watch for this issue. I have tried using two different client machines as well as Firefox and Chrome. I do a lot of web testing, so I do not cache webpages. I thought of Solr. (Dumb Question) - Does JSPUI use Solr as well? If so, do you have specific logs and things to watch, if Solr is suspect? The Java clear cache had no effect in improving the symptom (with the system in this present condition) I have also been sure to check that all of the Dspace working directory and Recursive directories are all owned by tomcat:tomcat. My install is using PostgreSQL. One possible error was that I installed DSpace as the root user. All my directories had to then be chown'd for Tomcat (8.5). I can't think of how that might affect this problem, but At least it is more information. With no further immediate suggestions, I will clear out my logs, do a fresh reboot, mess again with the database utilities (if needed) and leave it hands off and see what logs again when the problem returns. Thanks for the support!
