A website I work on recently posted a file at the root of their website named "2011.html." Now, any 2011 blog posts with the permalink structure of year/month/day/post-name do not work, and instead load the 2011.html file. Trying to bring up the archive at domain.com/2011/ also incorrectly brings up the file. 2010 and other years work as expected.
Is there any way I can use mod_rewrite to only acknowledge this file when 2011.html is explicitly in the URL, and use the standard permalink structure with every other URL so that the blog functionality is restored?
The link to this file was sent out in a marketing e-mail, and is receiving a lot of activity so it can't be moved or renamed.
