Failed to open filename.fmp12
I've had a few of our remote users try to open a FileMaker Go file, but they get an error in their Safari browser saying: "Failed to Open "filename.fmp12." This doesn't happen often, it happens very sparingly and I haven't been able to figure out what the cause of this is. The only solution I could find is for them to delete the file and then re-download it.
Does anyone know what the cause of this error is and/or a better way to fix this error?
