I know it was dumb, but I upgraded to Mountain Lion without expecting it to totally wreck my FileMaker server setup with Zulu.

Looks like Instant and Custom Web Publishing don't work, which I believe means Zulu sync is doa.

Do you know any better than me if they are talking about fixing this sometime soon? It would be a huge pain to downgrade my machine to Lion, but I'm not really sure what other options I have. Maybe I should run FileMaker Server in a VM, but that seems a bit lame.

I think you're correct about your options, sad as I am to say it. (I don't have any dirt on when they might be shipping a compatible version of server.)

I have the same problem.
Did not read the small print. It seems that FMS12 does not work in Mountain Lion, at least the web publishing part. Very annoying.
I will have to downgrade again... hmpphh

I just checked and the 12.2 update of fms works... uffa.
I just had to deinstall everything and reinstall, fms, zulu, the whole thing.
