Welcome to the Q&A Forum

When using the 'on-page optimizer' tool, I continue to get the same recommendation on every page to only use 1 canonical tag on the page. I'm not sure why there are 2 tags on each page in the first place so I don't know how to remove the one that's not needed.  Our site is on a WP blog and a sample page to view the source code would be: http://www.shilohstreet.com/blog/is-flipping-houses-smart-real-estate-investing.html Does anyone know why this is happening, how to fix it and/or if I should even be concerned with it? Thanks!
