When your permalink structure does not end by a trailing slash (/), all your links look like http://example.com/2009/05. Permalink Trailing Slash Fixer add the missing trailing slash.
Example
If you have a site with the following permalink structure /%category%/%postname%.html and your permalinks
look like these:
- Single Post:
http://example.com/my-category/sample-post.html. - Category:
http://example.com/my-category. - Archive:
http://example.com/2009/05. - Page:
http://example.com/about.
After activation of the plugin:
- Single Post: not modified.
- Category:
http://example.com/my-category/. - Archive:
http://example.com/2009/05/. - Page:
http://example.com/about/.
