canonical tag does not work.
 

I understand that wordpress automatically creates canonical tag.
My website also has a canonical tag but it does not work.
When I write my url without www does not make it to www.
Maybe I need to set something in atahualpa to make it work
Because of this google indexed my site twice

Thank you

this has nothing to do with the theme. You should do a google search of the topic.
