Hey, I just started using Piwigo and I am still getting used to some of the features. I did a quick search but didn't find anything, so sorry if this has been answered before. I uploaded a bunch of photos and used the folder synchronization. Some of the albums worked fine, but others have a bunch of missing images. When I right click > view image, it seems to be missing from the server. Some have the correct thumbnails, but the images don't display. Others have no thumbnail, but the image displays when clicking it.

I did enable piwigo_privacy plugin, but didn't care for the functionality so I disabled it. Hopefully, that is not creating the issue. I've tried re-synchronizing the folder, but it doesn't seem to fix the problem. I will share a couple of screenshots also. Any help would be most appreciated.
