I haven't been able to fix these sooner as I've been busy the last few days. I got it now.
The Voyager app (voyager.lemmynsfw.com) on the instance works as expected and updates automatically now.
Post listing settings (blur nsfw/auto expand images) are back again. I will not update Lemmy version before I patch new version so it will not be unpleasant as before.
Also we're having trouble with the donation platforms. We may be making a change soon. Friends who have donated from sites such as Github Sponsors and Patreon before, what do you think about making donations from sites such as fanbox.cc or subscribestar.adult?
Yes. It gets donations from any cryptocurrency and sends it to our Ethereum account. Much easier than multiple currencies. Also I can track crypto donations only in one wallet, which is here: https://etherscan.io/address/0x4e4af5dc2f86235ac496542c2a1c00f3c4de40c6
