Hey there.
I updated my local weechat to version 4.0 a few days back. since then I am not able to get it to run at all. At first it screwed my terminal settings and said, several spelling libraries were missing. After I installed them, the terminal prompt just resets. weechat -v says I'm on 4.0. Don't see a way to debug this, as dmesg and journalctl are clean. Do you have any idea, what I could try to do to solve this?
I did that. Weechat would start with an empty directory and i could copy some of my config files over. With some it was broken again, but the most important configs worked.
