Hello 

I am trying to do the same using TIA 15.1. I am able to upload my edited HTML fiels via the file browser. But it does not work for me to upluad the HTML files with an upload of the HMI program.

I tried replacing the WebContent.zip file in the "C:\Program Files\SIEMENS\Automation\Portal V15_1\Data\Hmi\Transfer\15.1\CP_7_9" director with my edited version as well as changing the HTML files in  "C:\ProgramData\Siemens\CoRtHmiRTm\Miniweb15.1.0\WebContent". Both did not change the web pages. Is there something else I migth miss?
