[Serusers] serweb and fifo

I've successfully installed serweb and am able to log in. However, once I do so, I get the following error: Warning: fopen(/tmp/ser_fifo) [function.fopen]: failed to create stream: Permission denied in /usr/local/apache/htdocs/serweb/functions.php on line 172 at the top of the screen, and the message "sorry -- cannot open fifo" in red letters on the webpage above the user's information. I'm wondering if ser or apache needs to be configured somewhere with the correct permissions or ownership to make this work. Thanks!
