Self-fixed, I use the migration proces but forgot to change the instance name in the function.php snippet.
Thank you anyway,

Hello, what about old files previously attached with the old version?
I can see the Attach button, but old files are not still attached to the post. How I can fix it?

Thanks in advance,
Ricky
