Thank you Kevin. The OJS scripts that I sue include in the top:

I have applied the patch, but with not too much luck. Users still getting “Your session has expired. Please login again.” I can see that the SID is generated and an entry is added in the tblsessions table and after login the user is really redirect to the user or editor page, but at the end his login is refused. Anyway, thank you for your help.
