Login URL error

ok, my store URL works, when I try to login 2 things go wrong:

  1. image verification is screwed up. I have to do a “inspect element” over the image, then get the image URL, paste it into my browser…
  2. then when the image comes up, I enter the code…and get an error from browser:

    “Oops! Google Chrome could not find www.yoursite.co.nzwww.yoursite.co.nz”

    obviously the URL is doubled up somewhere in the coding…but where and how to fix this?
