Whenever we have changed domain name then we need to change the embedded link to absolutre path with old domain name. To overcome from this situation and change/edit all the post…we need to execute this query on database:
set `post_content` = replace(`post_content`,’olddomain.com’,’newdomain.com’)
The posts table of particular blog, change all instance of olddomain.com to newdomain.com. make sure we use right blog ID of the blog in question.
