Thanks for posting.
I have a few questions regarding your Mac OS X 10.5.8 server machine.
What is the processor speed and RAM on your server?
Is Apache running a default configuration? Are any websites running through Apache?
You will need to make sure web sharing is enabled in Mac OS X 10.5.8. Under system preferences go to Sharing. In the Sharing window you need to have Web Sharing checked so it is on. If web sharing is off, it can cause an issue with web deployment.
Resetting the Apache configuration may also help resolve your issue. An Apache reset would wipe out any web sites you have running. You can reset Apache by following these steps. First, navigate to /Applications/Utilities and open terminal. In terminal, run the following command below.
sudo cp /etc/apache2/original/httpd.conf /etc/apache2/httpd.conf
This command will reset Apache back to default. In FileMaker Server 10, open the admin console and select edit server deployment. In the web deployment, select Apache as the web server and see if it will deploy now.
Thanks for your response, I appreciate it. Unfortunately I still can't get the web publishing to start.
The specs fo the server are: 2.66GHz, 6GB Ram.
Web Sharing is enabled, I have turned it off and then back on.
I have removed and re-added the httpd.conf file and re-added it.
I have reset Apache to it's original config as you suggested.
I have reset the httpd service numerous times.
I have also tried reconfiguring the options through the FM 10 admin console, all of which are correct.
I am still receiving the same errors and am wondering what else there is that could possibly be causing this issue and what else I could try to rectify it?
Thanks again for your help.
