strange error

When I clicked on a recent forum post and reply, I am getting this error.

Code:

DB function failed with error number 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '://houseboatingworld.com/forum/index.php?action=notify&topic=4529.0
", ' at line 2 SQL=INSERT INTO jos_jp_pages (original, sef, component) VALUES ("/index.php?option=com_smf&Itemid=28&action=notify&topic=4529.0">http://houseboatingworld.com/forum/index.php?action=notify&topic=4529.0

It wasnt the case earlier. What could have caused this problem? How to rectify it?
The replies are being posted anyways.

thanks
