en WordPress.com Forums › Support Updating the post thumbnail Author Posts September 8, 2012 at 2:25 am #1003803 paperiseMember Hi everyone, I am having trouble updating the thumbnails of my old posts (posted before the new theme change). Basically, if you look at my post wall, you will see my list of posts, with big grey boxes in top of them. They appeared after I changed my theme to Oxygen. However, the new posts have thumbnails that are working perfectly fine. I was wondering if there is a way I can update all the thumbnails of my older posts and get ride of the grey blank bloxes. Thank you all! The blog I need help with is paperise.wordpress.com.

However, I too would be interested to see a resolution to this issue. Many of the posts on my blog (hsjawanda.wordpress.com) feature large images (640 by x) and very little text. Yet when I tried out Oxygen, all it would show was grey boxes for all of my existing posts.

How did you fix it? Any help would be much appreciated :) Thanks! Author Posts The topic ‘Updating the post thumbnail’ is closed to new replies.
