Your ROOT_URL in app.ini is https://scm.trinitydesktop.org/gitea/ but you are visiting https://scm.trinitydesktop.net/gitea/TDE/tdewebdev/src/commit/1422b9e7a031f0a5e21f2e9e9689e7f6e3be3a62/kommander/editor/pics/small/customwidget.png
You should set ROOT_URL correctly, otherwise the web may not work correctly.
