a common process is to use the wizard at first time and then cross check the result for possible post editing. Therfore we do quick check the website structure with the browser web tools (F12) and/or the uiExplorer. To give you an example for a post edit task:
the next selector is detected by witzard with:
<webctrl aaname=' ' href='?page=2' tag='A' />
here we do see very quickly that it will not work for the other pages (e.g. specific page number)
so we do modify.
"<webctrl tag='A' parentclass='next' />"
same for an empty extract result: If an extract result is empty we do edit / check the selector and the extract metadata config.
However is now the extract for the italy items working at your end?
