Some of my users say their links not work,

I checked it and it's the way they say, for example one url of my user is always missing one letter at the end, i don't know why. even when i try to add it manually, it redirects me to the url with the missing letter.

Anyone can check or had similiar problem?

It could be this one : http://www.phpbb-seo.com/boards/phpbb-s ... html#16445

it is
thank you deeply this a issue with search.php was a PITA
