Removed sidebar but cant stretch out content

I have removed the <?php get_sidebar(); ?> already and that removed the sidebar. However, the images in my posts are still getting cutoff as if there was still a sidebar there. I am using the technetiumastic theme by padd solutions. I have spent hours trying to figure this out but can’t seem to fix this. Please help!
