That button is the original button for phpBB forums and is thus disabled since sourceforge.net is used for accounts. Is the sourceforge bar missing? Try clearing your cookies for this site. (If you still can't find the button, log in from another sourceforge page unrelated to this forum.)

yes, the aourceforge bar is missing. I deleted all cookies and enabled all cookies again and all I can imagine, but it's still missing on these 2 computers. On a third computer the bar exists (also FF).

Maybe it's an adblocker of some kind doing this. If all else fails, submit a ticket to SF about it.
