Hi Andrea, The error you described sounds like it might be this one: https://github.com/DSpace/DSpace/issues/9217
Simply put, in 7.6.1 (and some earlier versions of 7.x), you'd see these strange errors if you attempted to startup the DSpace backend (server webapp) while Solr was *down* (or unavailable/unresponsive). The fix/workaround was to simply start Solr *before* the DSpace backend. As of 8.0 (and the upcoming 7.6.2) release, we have fixed this issue and the DSpace backend can now start successfully even if Solr is unavailable.
