Programmer Joomla

There are several tasks.

1. You need to set up redirects on the site: from the version of the site with www to the version without, remove the slash at the end
2. Deal with 404 pages on the site. Notice that there were incomprehensible pages 404, it is not clear where they came from and why. They noticed, as they began to climb such pages in the search. Perhaps they should set up a massive rediect on relevant pages.
