more post user problem

[Cust0ms]

Hello,
When I visit a profile any user and click 'Show more posts this user' I receive such error:
Fatal error: Call to a member function parse_bbcode() on a non-object in /var/www/search.php on line 2871"

Where is a problem?

What is on line 2871 of your search.php page? Try disabling your plugins and then see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Try reuploading said file.
