I’m on sh.itjust.works, but I can’t see more than a few posts as well.

EDIT: Seems to be the language settings of the comm or the instance. If you choose undetermined, you can’t post in this comm. The same problem as with kbin posts/comments.

EDIT2: It’s the per user language setting. I had undetermined selected in my account and once I chose English as well, all of the posts started appearing. It might be that the posts were posted with English set up as the post language, not Undetermined, which would load for everyone, regardless what they selected in the language settings. But, if you post with a selected specific language, posts won’t show for those that don’t have that language selected in their settings.

There’s also a known wonkiness/bug with all and active sortings. Try sorting by new if you were using either of those two sortings.
