Either I'm doing something wrong (most likely), or there's a bug in how the URL's are processed when using the combo-box navigation.
When using text navigation, my monthly calendar shows fine. When using combo box navigation, I receive 404 errors.
- I've verified this with the TwentyTen theme, and disabling all other plugins.
- Tested with any WP permalink structure except for "Default"
- Pretty permalnks in the plugin itself is disabled
When using the text navigation <- May 2011 / July 2011 ->, the format of the URL is as follows
When using the combo box navigation, the order of the parameters is altered, and I believe that's where the problem lies. Note the following URL when using the combo box navigation
If you notice, not only is the order of parameters different (which ultimately isn't a dealbreaker), but the first character following the category is an ampersand, whereas when using the text navigation it's a question mark. If I change the ampersand to a question mark in the latter example, a 404 error is not returned and I see the large calendar I'm expecting.
