Updating attachments broke most images

Trying to update attachments break most of my images. See here

URL: thealtreview.net/galleries

as you can see, it takes forever to load, and when it finally does, you can see a lot of images are not there.

Not sure what to do. No I don’t have a back-up from before activating the plug-in – I just restored this site after 2 years of it not being live.

I keep getting this error, no matter how many times I keep trying to run it – “Error Updating Attachments — We ran into some errors attempting to update the attachments for all your Media Library items that have been uploaded to S3. Please check your error log for details. (#2)”

Thanks for any help.
