Hello, First let me apologize if this is in the KB or somewhere in the forums. I searched, but was not able to find the needed information. By default, I was under the impression that all file names would end in .php. We have a user who's files are now being published in .html instead of php, and this is generating 404 errors. I've checked the settings in the "Step 4. Edit" section of the builder, but it only allows you to change the file name before the extension, not the extension itself. Any input on the above would be appreciated. Thanks.
