htdocs/forum/includes/class_postbit.php(296) : eval()'d code on line 39

[toxotes]

I get the following error during invoke of the forum

"htdocs/forum/includes/class_postbit.php(296) : eval()'d code on line 39 "

First I thought that it might be up to an unbalanced brace in class_postbit.php

PHP Code:

if (!empty($this->highlight) AND is_array($this->highlight)) // AND ($_REQUEST['postid'] == $post['postid'] OR empty($_REQUEST['postid'])) ) 


However, the unbalanced brace matters only when the comment is uncommented.
I tried to use

PHP Code:

 php_value display_errors 0 


but it doesn't work since the hoster does not allow this on shared servers.
Any ideas how to solve the issue?

Thanks in advance!
