Upgraded the Filemaker server machine from MacOS 10.9 to MacOS 10.12, now the container field PDF's are blank. The Filemaker Server software is 13.0v5 x64. The client machine is using FMP Advanced 13.0v5. Everything was working great until I upgraded the operating system on the Server machine. I tried removing the files: Adobe PDFViewer.plugin and Adobe PDFViewernpapi.plugin, that didn't help. I have check all the FMP problem threads to see if there is a working solution to my problem. Nothing has helped. Any ideas?
