I've got an error message 'Handler "FMIPHP" has a bad module "FastCgiModule" in its module list' on the web after I've upgraded FileMaker server from v16 to v17 on Windows Server 2012 yesterday.
I've found this article saying that go to the IIS > Handler Mappings to change the permission from 'Read' to 'Read/Write' (see attached image). However, there is no such option 'Read/Write' to choose from. What am I missing here? All I'm trying to accomplish here is access my custom php pages from FileMaker Server 17.
