We have several Form Applications with Ajax events that worked fine under SC8.1 / php 5.6 Running SC9 v9.0.014 under Windows IIS and php 7.1.7, ajax events do not work and result in the following error messages in the php error log. Switching to php5.6 make the ajax events function correctly. This seems to be a php backward compatibility issue that surfaces with ajax events in form applications.
