Crash

[raffaem]

I followed the instructions but I get this error message on <Plug>NvimagerToggle:

1 change; before #494  2 seconds ago

this is because you do not have an XDG_CACHE_HOME variable set in your shell environment. you can add something like

export XDG_CACHE_HOME="$HOME/.cache"

to your shell config and it should work

Hello,
thanks for your answer.
Now it doesn't crash. I think that should be the default value if the variable is undefined, and in any case it should give me a more detailed error message.
It doesn't crash but it doesn't do anything either. I don't see any images and no error messages either after activating the plugin.
There seems to be no :CheckHealth nvimager either?
Best
