Permalink Problem – 2nd WP Install in Sub Directory of 1st.

Based on a generally dysfunctional development process, I’ve ended up creating a 2nd wordpress blog in a subdirectory of a first. So, basically I have 1 WP install at http://mysite.com/ and another at http://mysite.com/sub/.

The 2nd install in the sub directory is running on its own database, and everything seems to be working – except for pretty permalinks on the install in the sub directory.

I assume this is a .htaccess issue, but can’t get much beyond that. If I enable pretty permalinks on the 2nd install, I simply get 404 error pages from the root install.

My original WP .htaccess looked like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

And when I enable pretty permalinks in the 2nd sub directory, it wants me to add this to my .htaccess:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /contractor/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /sub/index.php [L]
</IfModule>

I tried just adding this code below the other, but that didn’t seem to do anything – and now I’ve more than exhausted my knowledge of .htaccess files.

Any suggestions?
