Hi
About categories, I don't know what you mean... Isn't a good practice to show canonical on categories?
No more than on any other page. You can always include a canonical to each page themselves but that does not really serve any purpose.
Which page should have canonical to which page exactly?
One more thing, I see that in pagination only works the first one:
https://blog.xxxx.es/
https://blog.xxxx.es/pagina-1
But if you click on the next (I expect to be https://blog.xxxx.es/pagina-2) it takes you to https://blog.xxxx.es/pagina-1
There can be 2 reasons for that:
1. The most common reason is that there was a change in number of items per page or similar pagination-related settings and URLs were not deleted since then.
So the first thing to do is to delete all URLs with "pagina" in them from the SEF URL manager, including all duplicates (ie use the button "Delete with duplicates" after selecting URLs in the list, not the regular Delete button.
2 - your template (or an extension) overrides the Joomla JPagination class. sh404SEF needs that to to compute proper pagination so if your template does it as well, we're in trouble. The way to check this is:
- Temporarily switch to one of Joomla default template, like protostar
- Purge all URLs, or at least the ones with "pagina" in them
- navigate to home page to have URLs created again.
