Hello Admin,
Thanks for your reply.
I had tried both method as you suggested. mod_security and manually replace code in files. unfortunately both didn't worked.
I would like to bring your attention on given url
not working:
http://www.plumbers.co.nz/forum/classifieds&sa=placebuy&id=6working:
http://www.plumbers.co.nz/forum/classifieds/sa=placebuy&id=6as you can see the difference between url is query string separator in first url there is classifieds&sa=placebuy and in second url there is classifieds/sa=placebuy
I didn't understand other add on are working fine with SEF but not classified.
I didn't changed code apart from what you suggested above.
I have attached respective files, would you please go through them and help me.
Regards,
