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.
