Smiles, attachments and 'icons' are broken in post

[Ruggy]

When a member or myself tries to create a post or reply to a thread, suddenly all of the smilies and post icons are broken and when I attach an image to the post or reply, the attachment image also appears broken.

I am using the theme called 'square' on MyBB version 1.6.15 and the images are all placed inside '/images/square' but are now broken. Here is a screenshot of the problem and could someone help me? thank you

This is the broken smilies and icons:
