571339 Buddypress comments not posting

hi there I have Buddypress installed on a client's website. When I try to leave a comment I get sent to a 404 error page and the comment doesn't get added. I need someone to find the problem and fix it as quickly as possible with the least possible interference to the client's website. The site is sewthisandthat dot com dot au To be eligible for this project you must quote "pinky" - if you dont you wont be considered regardless of your price or feedback. You must also be able to fix this issue in the next 4 hours - no longer. I have a number of client wordpress sites that I handle for them, plus I run my own WP Multisite with Buddypress. If this project goes well I'm more than happy to give you more projects as I have a list of adjustments and changes on my Multisite. thanks Stef
