Wordpress error

hi all,

i honestly don't know if this plugin caused this but it was the last plugin i was using before i noticed this error.. it could honestly have nothing to do with wpmu plugins but i thought MAYBE one of you guys might know and help me figure this.. i have been trying to figure it for hours now...

i also used site wide text change right before using blog templates plugin...

when i try to delete a comment it gives this error:

Fatal error: Call to undefined function auth_redirect() in /home/xxx/public_html/xxxx.com/wp-admin/admin.php on line 66

any ideas?

thanks in advance,
g
