i have started a new website on wordpress, im having problem with Yoast Seo Plugin. when i open sitemap url i get this error: Error 404!
Just deactivate the plugin and then reactivate it. If the problem persist visit yoast support team or forum.
You don't need the Yoast plugin at all. There is a great plugin for the sitemap which is called "Google XML Sitemaps". Just install and activate it and it will create the sitemap automatically. The other thing that you need to set is your blog home page and post pages titles. I mean the <title> tag. Please let me know if you don't know how to do and I will let you know. If you take care of these two things (sitemap using the Google XML Sitemaps, and the <title>) then you don't need any SEO plugin.
