The forum uses cookies.
I have the following settins at siegesoft:
block cookies - no
cookie duration - However the servers set them
block scripts - no
Send your Referrer information to servers? - yes
user agent string - use your real user agent string
I tried various combinations to no avail.
It is interesting that I can log in and check my sent messages, but I cannot read my received messages and access the forums. I suppose there is something that must be done to the ubbthreads configuration.
