Moved testsite to live site and photo links are broken

Some of the photos show up in the Visual Editor (in Headway) but not on the actual site. I went into the URL (in ‘inspect element’) for each photo and removed the “testsite” part of the URL. The photos still don’t show up. I’m not sure what else I need to do. I found this statement at the bootom of the Inspect element section but have no idea of how to fix it! [i]WP Super Cache link is installed but broken. The path to wp-cache-phase1.php in wp- content/advanced-cache.php must be fixed!

Help! We are ready to go live in two days!!

we can’t give you much input if you don’t tell us your url

sorry- I am new to all of this.

But I finally figured it out. Maybe the long way, but I changed the coding for each of the pictures in the site. It is working now. Thanks!
