When I tried to use search engine friendly URLs (permalinks) on both Wordpress and phpLD the URLs wasn't corretly redirected. It did work if I didn't use SEF URLs on Wordpress.
To solve this problem I had to create (change if you already have one) a .htaccess file in the directory my Wordpress installation was placed.
Example:
Your link directory is placed in the root: http://www.rootphpld.com/
Your Wordpress blogg is placed in the "blog" directory: http://www.rootphpld.com/blog/
In the "blog" directory you put the .htaccess file with the following information (If WordPress installed in a subdirectory called "blog". Change blog to whatever the namn is of your blog directory) :
# BEGIN WordPress
RewriteEngine On
RewriteBase /blog/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
# END WordPress
