I'm trying to open some files I created in an older version of InDesign in the current version. All of the photos are appearing with this black box and coloured lines. The links to the photos are not broken. Does anyone know what the problem is?
There is some damage in the image file or its data structure. what happens when you open the image in Photoshop?
if it looks fine, save it as PSD or TIFF with a new name and replace it in InDesign. If it looks the same, it is more serious. You have to take the latest backup which is ok and replace it with that.
You have to chech if your disk has some problems. E. g. Dropbox has a feature which caused many problems in the last two months. In synchronization (in its preferences) you can define the rarely used files are only saved remotely. When those files are called they should be transfered to the local disk. When InDesign takes a partial availble file and thinks it is complete it could also happen. Should not be, but it is worthy to check it.
