I have just bought the developer subscription for $99 and downloaded FMSA 12. I have tried this on my iMac and MacBook Pro and I get the same error both times. Both computers are running Mac OSX with the latest software and java updates.
Things that I have checked so far:
1. Running the latest software updates.
2. Apache web server (Web sharing on mac) is running and working.
3. I uninstalled FileMaker Server 11 advanced using the uninstaller before I installed FileMaker server 12 Advanced.
4. I installed FileMakers PHP software rather than selecting to use my existing installation.
I can't think of what else to do.
I had this working on my installation of FileMaker Server 11 Advanced on both computers prior to installing FMSA12.
Has anyone managed to get web publising to work and in particular on Mac OSX 10.6.8?
