the phpbb_config is the same as on the old server and there it worked fine.
I can also login to admin-panel cause when you login to forum the session-ids are appended to the urls and you can read and write in the forum as normal.
But this works only so long the session-id is appended to the url. Do i remove it or follow a link which has no session-id added the user is logged off.
On my old server there where no session-ids on the urls and it worked well with the cookies.
Now it seems that every time i do a login a cookie is created as it should be. (as postet on top) But on the next click it is destoyed and the forums function "append_sid()" adds the session-id to all urls.
