Solved: Custom link not working

Hi,
I have a problem with my gitea. Its running in a docker container.
I’m trying to get a custom link but its not showing up on the webinterace, but its accessible via http://gitea.mariojacobi.de/impressum.html . So it seems to work kinda?
Anyone got a idea what could be wrong? Do you need further details

Ok thanks to lafriks in the discord chat I fixed it the problem was that I created a linux symlink for the .tmpl, maybe one could improve the wiki. Will try to do it myself.
