Exception Type: TemplateSyntaxError at /
Exception Value: Caught IOError while rendering: (13, 'Permission denied')

What does it mean? how can i solve it?

回答1:

The user, Apache is running under, has no permissions to write into your /tmp/ directory.

My suggested approach for it would be following:

Run the Apache as a proxy to the daemon process under a non-root user.
Change the log folder from /tmp/ to some sub folder within /tmp, say, /tmp/projectname
Add the apache user, permission to write into that folder.

回答2:

Normally this could be the file permission problem while rendering

do chmod 777 -R to your template directory.

Or Did you upgraded your django version?
