It's taken my images linked in my posts from my gallery and unlinked them. I solved the problem with the header by reuploading the same image, and even on my landing page, did the same thing. But as I'm scrolling down through my blog I notice missing images that are in my media gallery, not linked to the posts I inserted them in. This is frustrating- I am a writer that needs this site running smoothly, it's fledgling. I need it working again.
