"Not a valid URL format' error when creating new application


I am trying to create a new twitter application for use with a website. I am currently developing the site locally, but when I try any of the following Website addresses the “Not a valid URL format” error returns:

Then I tried using the web address for another website I created, but that also returned the same error:


Any help with this would be great.


I just tried another application and am getting the same error when I attempt to put in any URL. I have made sure there are no proceeding spaces in the URL or spaces after the URL. I have tried addresses with “www.” and without. I have absolutely no clue why it will not accept any URL address I put in the field.
