Thanks for posting.
Just to verify, are you running FileMaker Server 11 Advanced v1 or v2? Currently, only FileMaker Pro and Advanced have v3 updates.
Also, I have forwarded your post to our Development team. I will update when any applicable information is made available to me.
I stand corrected. The running version of my Filemaker Server Advanced is 188.8.131.52. I've re-installed a couple of times, thinging remanats from the former v10 server advanced might be causing the issue... I thought I'd patched it to the newest release, which as pointed out by tsturtle is v2, not v3.
