Solution needed for : Database error due to bad parsing of variables

[cinq]

Some sites that have linked to certain pages I have on my site are wrongly parsing the & symbol in the url , instead giving such a link like :

PHP Code:

[url]http://www.mydomain.com/forum/articles.php?action=viewarticle&artid=1[/url] 


Instead of this :

PHP Code:

[url]http://www.mydomain.com/forum/articles.php?action=viewarticle&artid=1[/url] 


and as a result I am getting many database errors and well as visitors getting the error page.

Is there anything , on my end , that I can do to rectify this problem ?

Help most appreciated
