You are both stars. I imagine the Application.cfc that I had found was simply a template file. Placing the file in the root directory causes it to be picked up. Is this file only used by any script in the same folder, or does it also serve as a default for scripts in sub-directories.
Edit: It is not a template. The strange thing is that the other file must be referenced in some way, because without it other elements on the site break. I am happy to work with the suggestions for the time being, though.
Your help is much appreciated, both of you. Is it possible to mark a couple of your comments as the solutions?
I can only mark one solution, so I will mark this comment but thank both @Julian_Halliwell and @cfmitrah for the comments, as they led to the solution. Without their help, it would have taken way more time than I had available to resolve this.
It think it’s worthwhile reading the thread, because no single solution was found by one post. I have “liked” the comments that were most significant in reaching a conclusion. Thank you both for your help.
Please note that the application is not my own, and I am not myself making changes. I am just responsible for migrating it to a new server. A separate developer (not the original one) is responsible for the original coding.
The Application.cfc file that is in WEB-INF has been reverted to it’s original state. Without it, the site does not function. Should the original developer not have created a file there, or is that file a system file that should never be altered?
