After I moved my blog I found myself that I can’t access the “attachment link” of images from the Media Library, it directs me to a link that look like this:
http://www.mydomain.com/?attachment_id=3468
And if I click it throws me the following error:
Error: no image was specified
This happens from the imported and for new uploaded images. The same happens if I put a gallery and choose:
Link thumbnails to: Image File [X] Attachment Page
Error: no image was specified
And works ok if I link directly to the Image File.
