After php 7.0.1 installation (successfull) i can´t edit filemaker server´s deployment anymore. on test step, there´s a message: "The FileMaker installation process was unable to communicate with the web server.". Someone knows how can i fix this?

Install a supported version of PHP?

FMS14 is not designed to work with PHP 7.0.1:

OS 10.10 users need PHP 5.5.14
OS 10.9 users need PHP 5.4.24

thank you. reinstalled, it´s ok with PHP Version 5.5.36

At least 15 works with PHP 7 even if it is not certified by FM. Maybe 14 as well.

If you're an experienced PHP developer, with complete control over your servers, I say do what you want...

For the less knowledgeable, sticking to what FMI suggest makes life a lot easier.

I would not modify the web server on the same machine as FM Server. If you want to run PHP 7, it is best to install on a separate server, and access the web publishing engine on its own server or instance.
