Hi Martin,

We have been making changes to improve how the server notices new resources, like HTML files. It's possible that newer versions will pick things up automatically while older versions would not.

Where is your module located, relative to the "modules" that contains the standard set of modules? Are you doing any kind of Ant build or other steps to deploy it?

Another difference may be whether you're running your server in development or production mode. Production servers are more aggressive in caching resources for performance. This is controlled with a -Ddevmode=true option during Tomcat startup. For more details, see the "Configure LabKey Development/Debug Configuration" section here:

https://www.labkey.org/wiki/home/Documentation/page.view?name=build

You can check the mode of the server in the Admin Console.

Thanks,
Josh
