OK, I added the code but it expanded the body of the website content to fit the window (messed up that formatting) and did nothing to the menu bar, header or footer.
Sorry – where should I add this?
I am having the exact same problem on my site as well with regards to the images aligning to the left regardless of where they are set to align in the post/page (most of the time center or right). Also, it seems to add some additional breaks above the images as well whenever the plugin is enabled.
I tried the fix from synchronista above and it shifts everything to the right now so this does not fix the problem.
