If you are hosting multiple cakephp websites TOGETHER with your wordpress in one single domain, you might encountered some errors or incorrectly display css or images in your cakephp web application.

This is due to the default mod_rewrite rules  that come with cakephp installation as it is assume that the application is running for one domain name only.

Fortunately, it is possible to amend that mod_rewrite rules to allow apache to customise different routes for different applications.

Before I explain on how to do it, lets see how I configure entroducing.com

www.entroducing.com -> will call default wordpress (this blog)
www.entroducing.com/project/app1-> will run app1 cakephp
www.entroducing.com/project/app2> will run app2 cakephp

In the webroot folder of your cakephp application, edit the .htaccess file and add the following line

RewriteBase /[subdirectory]/[applicationname]

And it should looks like this

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /project/stepup
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

Save the file and test your application. It should works fine now.
