Shadowbox JS doesn't load

@mtbmtb:

The file at https://isocnews.com/wp-content/uploads/shadowbox-js/41e05a70f924497be53687a3f0b7e31e.js is returning a 404. Try checking to make sure that wp-content/uploads/shadowbox-js/ exists and has proper file permissions. Then delete any files inside of that directory. After deleting any files, visit Settings->Shadowbox JS in the admin and just click save changes and try the site again. If that doesn’t fix it check the file permissions on the file created in wp-content/uploads/shadowbox-js to make sure that the webserver user can read it.
