I gave a deeper look inside the sources of ExternalConnector.cpp and WebInterface.cpp.
Default config-file is remote.conf. If you got an old one (before changing templates to php), just erase it or do the following :
* update amule.conf through the GUI's preferances pannel, tab "remote control", to setup amule.conf with needed parameters (port, password, template).
Then run amule-web with the following :
amuleweb --create-config-from=~/.aMule/amule.conf
This will generate a brand new remote.conf appropriate to your current settings.
To change the template, just update the section [Webserver] Template inside remote.conf with the name of the desured directory in /usr/share/amule/webserver.
Then simply run amuleweb to enable your parameters.
Suggestion : could we have a "Template" textbox or combo box in the GUI panel, instead of updating it manually in the conf file ?
And of course, thanks for this great piece of work.
[EDIT] miscellaneous corrections, thanks stefanero, and thanks to GonoszTopi for added complements.
Maybe these little things should be added to the wiki, as this one is a bit shorty on the use of amuleweb ?
