Thread: Problem with navigation bar

I created a tab nagivational bar and when I click on most links after publishing, it is adding a 20% symbol to the URL and going to a 404 page.

For example:
www.sample.com/page.html

converts to:

www.sample.com/20%page.html


Thank you foor your help.

20% means a space so just remove the space in the links and republish
