How to reset MSM web server used for guest portal

[tdasher]

I've configured a guest portal on a team of 3 MSM765 controllers that works properly but need the actual web page to look different than default, i.e. accept a list of Ts&Cs, etc.   Downloaded the zip file with all web content and made the needed changes, uploaded to the team, and even verified by viewing the files from the web management interface that they were properly uploaded.

Unfortunately, the new content is not being served up.  Rebooting the controllers is not an attractive option as they're operating in a 24x7 environment.  Is there any other way to get the controller team to start using the new content.  This really shouldn't be so difficult but unfortunately it seems to be.
