Thank you for the post.
To confirm, FileMaker Server has been completely removed from this computer and now the Apple Mac OS X web server (Apache) is not functioning correctly?
If the above is true, then I would suggest contacting AppleCare for assistance with their software:
If I misunderstood and the issue is related to FileMaker Server, please clarify and I will do my best to assist.
Thanks for getting back to me. I contacted Apple Support and we spent quite sometime trying to figure out exactly what was happening, from what we can tell when FileMaker Server was uninstalled it effected Apache somehow, while it appeared to be working it wasn't responding to any requests. In the end the only way to fix the problem was to do a complete reinstall of the operating system. I have to say this was not a lot of fun.
Now I have a new problem, all may web pages are on the mac running OS X server all the data bases are on the mac running FM 13 server and I can't seem to get the two to talk to each other. I have to say upgrading to FM Server 13 has been a nightmare! At this point my bosses are seriously considering dumping Filemaker in favor of something else. This is putting me in a difficult position because I was the one championing FM.
