No matter, what I try, gitea is ignoring the external renderer.
Config in app.ini
ENABLED = true
FILE_EXTENSIONS = .adoc,.asciidoc
RENDER_COMMMAND = “asciidoctor -s -a showtitle --out-file=- -”
IS_INPUT_FILE = false
Also tried asciidoc, RENDER_COMMAND with and without path.
As nobody else has this problem it is something stupid, but I am at a loss.
