Blog page will not link from widget or sidebar social media

I have a blog post page on my website. I have entered the blog page url in the HighEnd options settings under the social media >blog section

On my footer and side bar a have a link where you can go directly to my blog page. The link will not work. You are directed to File not Found. I have tried everything I can think of and can not come up with a solution. I do not want a broken link on my website. Thank you ina advance for you help.
