I had switched theme of my blog, but when i opend my blog i saw there that thumbnail of posts( featured image) are not showing up.
I moved to my old theme back but images are still corrupt showing. However when i'm opening my posts every image is there showing perfectly.
I'm also unable to upload new image from my media section because after uploading it gets corrupt automatically.
My blog is http://mytechflow.com Plz help me guyz.
