as promised a my conference reviewer found another issue: evidently the upgrade from 126.96.36.199 to 188.8.131.52 was not perfect. Anyway I prefere to refer to his own words (he's a reviewer that try to upload his comments on a paper):
"The problem is when I try to save the recommendation (accept,.....reject) and the score from 0 to 100. When I try to save the message is the following:
Fatal error: Call to a member function getDateAssigned() on a non-object in /ocs/classes/submission/reviewAssignment/ReviewAssignmentDAO.inc.php on line 486"
I saw the bug report http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=5373
that seems quite similar (and I hope the similar solution).
Any idea to solve it or go around? My bigger problem, as you know, is that I cannot access the server as admin (so I can play in someway with the configuration but I am not enabled to use command line tools and to run any exe prog) and this limit me with patches use.
