Your ROOT_URL in app.ini is https://scm.trinitydesktop.org/gitea/ but you are visiting https://scm.trinitydesktop.net/gitea/TDE/tde-i18n/src/commit/4b3f5f0d5f3fda3022ea1abc566077e3d6ac5c4b/tde-i18n-es/docs/tdeedu/kalzium/timeline.png
You should set ROOT_URL correctly, otherwise the web may not work correctly.
