i am a novice user.. i may suggest you to open blog/conf/_advanced.php

and

1.change:

$cookie_path = preg_replace( '#https?://[^/]+#', '', $baseurl );

to

$cookie_path = false preg_replace( '#https?://[^/]+#', '', $baseurl );

2.and/or change

$cookie_expires = time() + 31536000;

to

$cookie_expires = time() + 1;

i hope it works... give it a try until pro guys deal with it.. and u better state you b2evo version..

the 2nd way should work i guess... it does not disable cookies, but keeps cookies as short as possible.. keeps for 1 sec instead of 1 year

Its not working any other idea?
