I have problem. I want to change html code of my joomla module, but I already have that module installed, and I need it. When I try to install changed version I got message that I already installed that module, so i guess that I need to change some names in xml file, but i don't know which ones.. Can anyone help me?

Check your Joomla module xml file have method="upgrade":
<extension type="module" version="3.1" client="site" method="upgrade">
