Single letter, lowercase link attribute doesn't work

I accidentally posted this in the wrong place earlier today - sorry! I think this is the right category for my question!

I am creating a "glossary" on my MODx site and for some reason, I cannot use a single, lowercase letter for the individual letters of the alphabet. When I use a lowercase, single letter as the "link attribute" for any of these 26 pages, it actually breaks the entire site. I am using Wayfinder and when I make this change all of the link URLs are all rewritten incorrectly.

I would like to stick to a strick, "all lowercase" policy for the urls on the entire site. Does anyone have any thoughts as to why this isn’t working?

Here is an example:

e.g.;
This will not work:
http://www.mysite.com/glossary/d

and this does:
http://www.mysite.com/glossary/D

Thanks in advance for your help!

Non case-sensitive urls
If you want your urls to be non case-sensitive, you need to do the following change to the .htaccess file:

Replace:

RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
With:

RewriteRule ^(.*)$ index.php?q=$1 [L,QSA,NC]
So add NC to the rewrite rule settings.

Sorry for the confusion. Unfortunately, I am no MODxPert.

Here goes: I am trying to use a single, lowercase letter for the "Document’s alias". But it sounds like writing the "non case-sensitive" rule into the .htaccess file may be the answer. I will see how that goes and report back.

Thanks for you help!
