I’ve moved @dh42’s post here to keep the other thread clean, as this seemed the most relevant place for it.

Hi David,
Sorry I missed your post at the time, I’ve just worked out what’s going on with some attachments failing while others work fine.

It seems to happen when you try to add images via the Quick Reply box. If you hit the Go Advanced button instead, you’ll get a new page with an Attachments section below the message box. There’s a Manage Attachments button there, and using that to upload (or manage previous uploads) works fine for me - tested in Chrome on desktop.

As I mentioned in another thread, this has been a long-standing quirk. I’ve got bigger upgrades coming, including a proper migration to a new platform, and I’ll share more on that soon.

In the meantime, to try and reduce the confusion for new members when their images don’t appear, I’ve removed the attachment icons from the quick reply header for now. Not ideal, I know but at least it should save people from hitting the same frustration until the proper fix is in place.

Thanks, again for your patience and for sticking with it.
