Attachments should be fixed now. It took a lot of digging, but I found the culprit. One of the plugins (not sure which one) modified the functions.php file in a way that messed with its file format. I installed the PHP Files Cleaner plugin to track down the problem file, and it automatically removed the UTF-8 BOM formatting that was messing everything up.
Someone else had a similar problem. If anyone else has a problem with attachments giving an "image... cannot be displayed because it contains errors" error message whenever you click on them, this should solve it.
