I recently updated a page on my website and because of a contact form I added on the page the adress to that specific site changed from html to php. This became a problem when I surfed on my website and discovered that the only way to get to my updated page is if I type in the adress with php-ending. If I just click in the menu on top of my website to get to this page, my website types in the adress with the old html-ending and it gets to the non-updated version of the page.
How do I get my website to direct to the php-page instead of the old html-page when I click on the menu?
Thanks!
