Duplicate content with WordPress URLs both lowercase and Capitalized?

Any Wordpress pros out there that can tell me why I am seeing duplicate content issues in my GWT account due to one url being in lowercase and the other having capitalization? This is happening on several pages.



How does that even happen and why is Google saying duplicate content?
Both links take me to the proper page - but the lower urls are all that have
ever been created? Where are these capitalized versions coming from?

Thanks in advance. Appreciate the help.

I don't use WP, but my guess would be it happens because MySql is case-insensitive, so when the URLs with uppercase characters are rewritten to WP it's finding the info it's supposed to and serving the content.

Personally, I'd use a PHP redirect (rather than mod_rewrite) to correct it by sending visitors requesting URLs with Caps in them to the lowercase version.

Also you can use canonical metatag

I don't think it's canonical - because I have the canonical tag on every page.

And I'm getting weird duplicates with tags like this:
