Template i use (some template that i found in internet and customized) uses standard (default) WordPress archive system. In the sidebar, i've placed widget with tag list (tag cloud). When i click on tag, the posts belonging to clicked tag are being shown, as an archive page.
But this archive page looks like normal start page and i want to customize it a lot.
I now that i must use archive.php file to achieve this, but i don't know how to set this file, to be included after clicking on prefered tag.
I've browsed through my template code and didn't found any code line that would help achieving this.
So i'm asking for help - what function and where i should to put into my template code to include the archive.php (the archive page with listed tagged posts on it) to be shown everytime guest will click on tag to show posts tagged with it?
