https://treeherder.allizom.org/credentials/ and https://treeherder.mozilla.org/credentials/ Give an HTTP 500, due to: TemplateSyntaxError: Invalid block tag on line 7: 'static'. Did you forget to register or load this tag? https://papertrailapp.com/systems/treeherder-stage/events?highlight=763963325141901371&focus=763963325141901371&q=program%3Aapp%2Fweb.1 I imagine this will be a regression from the TEMPLATES config changes that had to be made as part of updating to Django 1.10: https://docs.djangoproject.com/en/1.10/ref/templates/upgrading/ (Even though I followed their guide, sigh)

Ah this is due to a missing `{% load static %}` statement - it was removed in bug 1273034: https://github.com/mozilla/treeherder/commit/ba8165c23934f65df3bbd809f75af94e77a2a258#diff-305591ed7394d1ff36503ffa74c7b32cL1

Comment on attachment 8833121 [details] [treeherder] mozilla:fix-credentials-self-serve > mozilla:master Shoot, sorry. My bad. Thanks for fixing this!

Commit pushed to master at https://github.com/mozilla/treeherder https://github.com/mozilla/treeherder/commit/ca1d11e0acbd567dddbb69411dc8878987a851c1 Bug 1336270 - Add missing 'load static' to credentials self-serve pages In order to use the `static` statement later in the file, the static tag first has to be loaded: https://docs.djangoproject.com/en/1.10/ref/templates/builtins/#std:templatetag-static This was previously achieved via `load staticfiles` (deprecated form), but that was accidentally removed in bug 1273034, resulting in HTTP 500s when the credentials self-serve pages were accessed.

I've cherrypicked to prod, will be deployed in ~10 mins.
