My .htaccess:
RewriteEngine On CheckCaseOnly On CheckSpelling On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUES
the problem is that rewrite rules ARE case sensitive. So your Rewrite rule should be:
RewriteRule ^[Bb]log/(.*?)$ /Me/profile.php?username=$1 [QSA,L]
and voila you are fixed.
mod_speling.so has NOTHING to do with this.
