…/author/admin Posts page not displaying correctly (Layout Problems)

Hi, I’m managing this website: https://www.incrediblechangeshair.com, which is running the Bloom template.

When I click on a “post author” (there’s only 1 on this site and it’s also the administrator), I come to a page displaying all the posts for this author, however the layout is all screwed up. The content and sidebar background pics are missing (content should be white, sidebar gray), and the content is spread across the entire page, pushing the sidebar down to the bottom. The actual content should only have a width of about 610px instead of the ca. 970px it’s currently taking up.

Here’s the link: https://www.incrediblechangeshair.com/author/admin

Here’s what a normal post looks like (correct layout): https://www.incrediblechangeshair.com/fw-woman-feedback

Looking at the HTML in Firebug, I can see that it assigns the ID=”content” with the class=”narrow column” to the content, yet both of these aren’t found in the style.css.

Any ideas on why it’s assigning a wrong ID or how to fix this issue? I’m also not sure which .php file to edit – which one is associated with the “author posts” pages.

Thanks for any help in advance!
