I'm using CEON URI mapping, and installed Word Press into a sub-directory of my site. Whe I activated Permalinks in Word Press it immiediately crashed. I have since found that If I deactivate the .htaccess file I am using to make CEON URI work, then my blog comes up. But of course at that point, my main site goes down.

Is there something I could add to the main site's .htaccess to make it not affect the Word Press sub-directory?
