Template-loader postmortem
Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.filesystem.Loader: / home/zhixing/templates/show_content/ Sina / 433.html (Source does not exist)
django.template.loaders.app_directories.Loader: / usr/local/lib/python3.6/dist-packages/django/contrib/admin/templates/show_content/ ellipsis / 433.html (Source does not exist)
django.template.loaders.app_directories.Loader: / usr/local/lib/python3.6/dist-packages/django/contrib/auth/ Templates/show_content/ omits / 433.html (Source does not exist)

what"s weird is that there"s no problem with permissions on ubuntu, and the path shown on the error page is so correct that I can even paste it directly from xftp to open it. The
project was developed on win10 before it was released to the server, everything is fine, and everything that needs to be changed has been changed. Includes the path to inherit the template.
Project uses Ubuntu14 + nginx + uwsgi + django

Did you forget to add the following similar path to the DIRS under

TEMPLATES?

'DIRS': [os.path.join(BASE_DIR, 'templates')] or 'DIRS': [TEMPLATE_PATH]
