Check the apache httpd.conf. I had the same problem and it was because Apache was running as user www, group www and /tmp/ser_fifo was only writable by root and group wheel, therefore I change in Apache group from www to wheel and it started running OK. That was my solution, perhaps not the most secure, but a solution.

Subject: [Serusers] SERWEB- Warning: fopen("/tmp/ser_fifo","w") - Permission denied

I haven't had this problem with serweb before but today my serweb>user_interface site is giving me the following error at the top of the page. Can't figure out what's wrong, everything seems to be intact. ser.cfg has fifo="/tmp/ser_fifo".
 
Checked this month's mailing list archive but seems like no one experienced the same problem. Any pointers will be appreciated.
 
*****On user interface site (logged in) ***************
