No media attachments found – WordPress Importer

I have been reading forum and noticed that a lot of people are having the same problem with “WordPress Importer”, but none of these posts showed solution. I migrated a entire website from one server to another using the same links/path, folder, same images.

The site is huge, so far It’s seems that most of the posts, pages, structures are showing linked images inside and the “upload folder” on the server (source) shows ALL the images correctly.

However, the Media Library IS EMPTY! The FEATURE image it’s not showing on post/pages anymore.

ANY HELP?? SOLUTION???

thank you!
