trouble loging - cookie issue

[maoreactor]

hey everbody.

i have upgraded from 3.0.8 to 3.6.8 after reading how to do so.
the upgrade went perfectly and now the board is working.

the only problam is cookie problam.

cookies are not saved and thats making loggin into acp/mcp impossible.
using: http://www.vbulletin.com/forum/showp...14&postcount=4

i uploaded tools.php to admincp/ and tried to do as said, but when i press reset cookie domain or path it leads me to an empty dark blue page with vb copyright footer and does not seem to work.

if anyone has a better idea it would be awsome
