There seems to be some kind of bug with the Subscribe and Block buttons in the sidebar. They're appearing for me as nothing but text. Here's a picture with the inspector open showing that there's no element at all.
Also, this only occurs from the community view. Going into a post displays the buttons correctly.
I don't know if this is a Lemmy issue or instance issue, all I know is that I don't believe it was an issue on another instance I was signed-up to.
Ah, okay. I guess I managed to miss it on my last instance. Or, well, I may not have been there for long after they upgraded to 0.18.0, actually.
