Udaraaka, I am hesitant to switch back to the original twenty eleven theme because I have made several changes on my child theme with the footer, headings, etc.
I changed the child theme style sheet to what ClaytonJames suggested and it did not resolve the problem.
I am baffled at what I could have done to make it like this. The site was running well and I don’t know what I could have done to it.
