We have not heard of any issues running on FileMaker 16. What version was running previously, when it was working? FileMaker 16 is more particular about security – for example, if you’re accessing your FileMaker 16 solution over a secure connection, the web viewer also has to be secure (i.e. it must start with “https://”). Let me know if that’s what’s happening. From what you’re describing, it sounds like it could be an MBS compatibility issue. Our latest version includes a recent version of MBS that should be compatible with FM16.03. You can also get the most recent version from their web site, and use soSIMPLE to register it.
For your second question, I’m a little confused about what you’re trying to do. The only time the default calendars come up is when you’re in the soSIMPLE Calendar Settings file. We don’t allow deletion of the default calendars because we use those from support purposes. However they won’t show up anywhere in your own solution, unless you’re specifically referencing them in the web viewer URL.
