# Turn on URL rewriting
RewriteEngine On
RewriteBase /

# Protect application and system files from being viewed when the index.php is missing
RewriteCond $1 ^(application|system|private|logs)

# Rewrite to index.php/access_denied/URL
RewriteRule ^(.*)$ index.php/access_denied/$1 [PT,L]

# Rewrite to index.php/URL
RewriteCond %{REQUEST_URI} !^(.+)\.(js|css|gif|png|jpg|jpeg|bmp|swf|txt|xml|htc|pdf|xls|doc|ico)$

# Remove the index.php file
# Ref. http://www.codeigniter.com/userguide3/general/urls.html

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

# Allow these directories and files to be displayed directly:
RewriteCond $1 !^(index\.php|robots\.txt|blog|opensearch\.xml|favicon\.ico)

Answer 1

something like.

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

see rewrite base how i have modified, and you now try to access both codeigniter and wordpress url
