Have you tried to log out of FileMaker Server Admin Console and log in to see if it appear?
If you file is not on the List you could also try a commando see if it is there
You can read more about that here
First I tried to log out by clicking on "Log Out" which didn't worked. There was a wheel turning on a red background, so something was continuously "active". This was also the case before as you can see on the attachment. So then I closed the FM Server window in Safari and opened again, and all was as to be expected (see attachments). I feel stupid not to remember that when something doesn't work as expected, most often a simple restart will solve the problem.
Thanks for help,
