I wish I had an answer for you but I don't. Instead I have a similar problem.
I, as Admin, can't logout and more importantly nobody else can login.
The login page is OK then it reports "Login successful" but the header is replaced by:
<b>Warning</b>: Cannot modify header information - headers already sent
by (output started at /homepages/2/d104721877/htdocs/starving-artists/sa2
/languages/english/login-inc.php:14) in <b>/homepages/2/d104721877/htdocs
/starving-artists/sa2/forums/photopost.php</b> on line <b>157</b><br />
<br />
<b>Warning</b>: Cannot modify header information - headers already sent
by (output started at /homepages/2/d104721877/htdocs/starving-artists/sa2

/starving-artists/sa2/forums/photopost.php</b> on line <b>159</b><br />
It returns the user to the home page but still has the "login" menubar.
Same thing when I try to logout:
Warning: Cannot modify header information - headers already sent by (output started at /homepages/2/d104721877/htdocs/starving-artists/sa2/languages/english/login-inc.php:14) in /homepages/2/d104721877/htdocs/starving-artists/sa2/forums/photopost.php on line 167
Also reports line 168, 169 and 170.
Any help would be greatly appreciated. Existing members are curremtly using (or trying to use) the galleries (it accepts registrations OK) but the site goes live in two weeks and it HAS to work.
