@iceman027: Hello there, The width of the posts are fine. Since the content of your sidebar don’t use of the full width there is an empty between the content and sidebar. Do you want this space to be used to increase the width of the content?
Yes, I want the space to be used to increase the width of the content. I tried making the adjustment in the live theme editor but it would not save. I think the previous additional CSS entries I made to the old theme could be the issue?
