Thanks for any contribution to this problem.
On my blog http://www.treadmill-ratings-reviews.com/blog when you click on my name on my posts it goes to http://www.treadmill-ratings-reviews.com/blog/author/Fitness%20Guy-2/, which leads to an error page. That author does not exist. Now my wordpress account has my username as "fredwat12", but it shows on my blog when you click on my photo on the upper right corner "Fitness Guy-2". How do I get that changed to "fredwat12" so the links point to the right author page?
The blog I need help with is www.treadmill-ratings-reviews.com.
