You created this against TracHacks, please specify the right component when creating bugs or the owner will never see them.

Also, this bug is triggered because the plugin is using Python 2.4 specific constructs and you're running Python 2.3.

[osimons]

Near the top of the tracfullblog/core.py file, could you add this import:

from trac.util.compat import sorted

Does everything work now?

(1) athomas: I am sorry for my mistake, and thank you for your correction.

(2) osmions: Thank you very much for your patch. I have tried the pache, and the first screen was displayed normally. But posting entry does not work.

NameError: global name 'set' is not defined

So I add the following line and post/read/comment/attach/tag works fine.

from trac.util.compat import set

Thank you very much! --yamasaki

(In [4102]) FullBlogPlugin: Python 2.3 compat fix.

Closes #3485.
