I upgrade from wpmu 2.6.5 to 2.7 using the codex instructions. Bt after upgrade my blogs are running fine but i can't log-in to my admin panel. After trying fora while i press forget password there when i give the user name it does not any confirmation massage bt when i put the email then send the confirmation link. Bt when i click on the link it shows some internal server error.
Can some please suggest me any solution immediately? otherwise i have restore the old files.
