Bad rewriting of contact-form

[switch42]

Hi,

 

I have problem with bad rewriting of page with default contact form from SEO&URL.

 

I have some links for CMS pages (like shipping, about us) and added link for contact form in Top Horizontal Menu.

CMS pages works fine, but when I click on contact form page, there is page not found.

 

If I click contact form page like the first, it works, but after clicking on CMS page and back to form, there is page not found.

 

I see the url of CMS pages for example: http://www.doprovazejme.cz/www/content/19-obchodni-podminky

 

and contact form url is: http://www.doprovazejme.cz/www/napiste-nam

 

After clicking from CMS page it tryes to redirect to this URL:

http://www.doprovazejme.cz/www/content/napiste-nam

 

I have Friendly URL enabled, did not change nothing in core.

 

Can you please tell me what am I doing bad? Or where is the problem, what can I do for repair?

 

Thanks very much!
