CodeIgniter Inside Wordpress behaving badly (htaccess issue?)

[eluser]blewis[/eluser]
I have an existing WordPress 3.x install in my root and I am now adding a custom CI application (ver 2.0.2) inside of that (subdirectory /ci). The CI install went fine, but I am having issues with the URIs. I believe it's an htaccess problem, but I can't be sure.

Wordpress htaccess:

Code:

RewriteEngine On
RewriteBase /

RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(ci).*$
RewriteRule . /index.php [L]

CI htaccess:

Code:

RewriteEngine On

RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

When I try http://www.mydomain.com/ci/index.php, I get my default controller...no problems. I can even get other classes without issue as long as the index.php is there (e.g. http://www.mydomain.com/ci/index.php/auth/login/ works just fine).

However, once I try to remove the "index.php" portion, it breaks -- I get the 404 page for my WordPress app! So if I just do http://www.mydomain.com/ci/, I get a Wordpress 404.

I have the base_url configured:

$config['base_url'] = 'https://www.mydomain.com/ci/';

I have tried numerous suggestions on various forums about changing the WP htaccess, but nothing has worked. I also tried adding a RewriteBase in the CI htaccess, but that didn't affect it at all.

Any thoughts? Driving me nuts!

thanks,
Bryan
