I have recently migrated a website from the Joomla CMS to the Squarespace CMS.
My internal file storage under Joomla was located at /files and /images; whereas under Squarespace it is at /storage/files and /storage/images.
Unfortunately Squarespace doesn't offer a sitewide 'search and replace' feature to change my links.
I have manually changed as many links as I can, but the site needs a comprehensive checkover to correct any internal storage links that are broken.
There are 700 items of content to check. If you want to take a look at the website, it is at http://www.menshealthaustralia.net.
