Basically have the same problem as, https://www.amember.com/forum/showthread.php?t=7929 My aMember installation is installed at member.domain.com My forum installation is at forums.domain.com EE is at domain.com The aMember works perfect with EE, login at the same time, however, it doesn't work with forums.domain.com I moved the amember installation to domain.com, so that it's no longer at members.domain.com on advice from the support staff (they said it had something to do with domain 'hierarchy'. Still the same, still won't log me into VB when I log onto VB. Please help, I would even consider paying for the help. Thanks.
