Hi Rubén, Have you reindexed your Solr Stats after upgrading? See step #13 in the "Upgrading DSpace" documentation:
https://wiki.duraspace.org/display/DSDOC5x/Upgrading+DSpace There are two steps to actually upgrading Solr Statistics. 1) The first part it to just upgrade the indexes (to the latest Solr version). This part is performed automatically by default (but if the automated version has errors, there are those "Manually Upgrading Solr Indexes" instructions. 2) After the Solr indexes are in the latest version, you ALSO need to perform an "in-place" reindex. This ensures that the structure (schema) within your Solr index is updated to how DSpace now stores statistics. If this is skipped, DSpace may not be able to "read" all the statistical data successfully, and so it may only display a portion of the data that is actually within your index. I hope that helps. But, let us know if you run into further issues. If you have already performed both of these changes, I'd also encourage you to check your DSpace & Tomcat logs to see if any errors are being reported.
