I found some issue with my local installation of alfresco share. When I try to login using
http://localhost:8080/share
it returns to me this error message:
I finally found the problem. As wrote on Alfresco forum, "Share will not let you log-in if the Explorer application is either not running correctly or running on a port other than 8080 and you haven't told Share where to find it. You must get Explorer (/alfresco) working before attempting to run Share".
thanks for your time, Andrea
