error with member post

[blieper]

hi getting a error while members are posting on a forum, normal guest dont get a error:

ERROR:
Warning: Variable passed to each() is not an array or object in /home/virtual/site2/fst/var/www/html/forum/thread.php on line 226

Warning: Cannot add header information - headers already sent by (output started at /home/virtual/site2/fst/var/www/html/forum/thread.php:226) in /home/virtual/site2/fst/var/www/html/forum/acp/lib/functions.php on line 80

SOURCE:
if($showuserfieldsinthread==1) {
while (list($key,$val)=each($userfieldcache)) {
$fieldcontent=$parse->textwrap($posts["field".$val['profilefieldid']],20);
if($fieldcontent) eval ("\$userfields .= \"".$tpl->get("thread_userfields")."\";");
}
}

Is this good ?

Cheers for the reply's

Please read the error messages:
1st Error: The variable $userfieldcache is not an array

2nd Error: The script cannot add header information because headers already sent

If you ask me if this is good, I would answer, no I don't think so. The best thing is, to fix these problems
