Fatal Error on one Browser, but not another?

[zinja]

This is wierd. I have a situation where certain versions of a browser (newest Firefox) is causing a website to not load due to a fatal error for an undefined function. I have looked at the error log and that is what the problem is. The thing is, if I use a different browser on that machine, or another computer - it works fine and no error is logged. I even have a user who cannot use either Firefox or IE to load the site, they both cause the fatal error message to be logged.

The site is

http://www.ar-mls.com,

and from where I am now, it works just fine. I have even vpn'd into my office PC (same ISP hence network as the user that can't use the site) and the site works fine with both IE and Firefox. Any ideas?

My personal saying - Just remember, it can always get worse, and usually will.

you'll be doing some browser sniffing that's causing problems.

It is like the whole site is falling apart. Could it have something to do with Zendoptimizer. I have restarted Apache, but it didn't help. Should I restart the whole server?
