Accessing a subdirectory

I have looked through every thread I can find on this issue and so far nothing has worked. Therefore, I am putting up my own problem.

I have a site with WordPress 3.2.1 in the root directory. I am trying to get a plugin (Event Espresso’s ticketing addon) that requires the folder /espresso-services to be placed in the root directory.

The problem is that I cannot access any of the pages in the subdirectory. I even created an index.php file with a simple php call echoing Hello and WordPress just gives a 404 error.

I have tried many of the different hacks posted in the forums to the .htaccess file and nothing has worked. The folder and files all have permissions of 775.

Here is the DEFAULT .htaccess file that I have:

# -FrontPage-

IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName vancouver.siggraph.org
AuthUserFile /home/vansig/public_html/_vti_pvt/service.pwd
AuthGroupFile /home/vansig/public_html/_vti_pvt/service.grp

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

# END WordPress

Any thoughts on how I can get these pages to show up?

Thanks
