django - django、夹层、nginx 中的 displayable_links.js 出现 500 错误

标签 django mezzanine django-tinymce

我在 displayable_links.js 上收到 500 错误。我认为这与我的 ssl 设置有关。使用 Django 1.9.1、Python 2.7.5、PostgreSQL 9.2.14 和 Mezzanine 4.1。发生在调试中和 gunicorn 后面。我有 * 允许的主机只是为了消除这种可能性。它也直接发生在端口 8000 上。

我的 nginc.conf:

最佳答案

它在 4.1 发布后的几天前已经修复。所以在 4.1.1 或 4.2 之前你需要暂时使用 master 分支。
