Don’t think a screenshot would be helpful. All posts are expanded, where as there used to be an option to have them collapse and show a summary instead of the full post. Links to posts give a 404 error now as well. Problems occurred with the 0.4 update.
Yes, 0.4 is a major update and there are many differences from previous version. I change the way content showed up in index and other pages with the_content(), previously, I used the_excerpt() and know the excerpt just showed up at search results page.
Maybe an option to choose whether full content or just the excerpt like the previous version would help. What do you think?
