Silly me, I missed to SUBMIT this post I wrote on 23th just after Alec's one.
I think what I aid it's still relevant in this thread ("login issue with multiOJS"), so I publish it anyway:
To be completely sure the code versions were synchronized I tried directly with the tarball you distribute from your PKP website (released as OJS 2.4.1).
With RESTful and without patching SessionsManager.inc.php and bootstrap.inc.php I'm unable to login in the Site (index) or the Magazine (trad241).
With RESTful and patching both files I'm able to login in the manager (trad241) but not in the Site (index).
In this last case, while user keeps logged in the magazine, when I visit links to the Site (ojs-trad241) I'm redirected to login at:http://revistes.uab.cat/ojs-trad241/log ... 241%2Fuser
In other words, I'm able to reach the magazine (as Journal Manager or whatever) but I'm unable to do anything as Site Administrator as far as any link is redirected to login page.
I'm pretty sure mod_rewrite is working fine (I'm testing new code in our production server and 2.3.6 is working like a charm).
The point is this issue sounds a lot like former one so seams to me that I'm missing something obvious.
