New pages starting with 'W' are not reproduced (404) on Chrome.

New pages, with a title starting with the letter W assigned to them, will not show up on the internet.

Website: www.debron.nu/w

Pages that will not show:
- http://www.debron.nu/w/index.php/will-paauw/
- http://www.debron.nu/w/index.php/welkom-2/
- http://www.debron.nu/w/index.php/wrattenbehandeling/

Thanks in advance for your advice

 

I had to solve the problem by changing the page-names starting with another letter than W, and sure enough this worked.
I have NEVER seen this problem before, have you ?
