    • Hi David,

      I want to make sure I understand the issue you are reporting.  You created a website that is based on the site you mentioned and in the new site (your site) the links are not working?

      It would simplify my investigation if you provide a simplified version/repro of the issue you are seeing and uploading it here.  I do not have enough information to see what is happening.

      Also, will you provide the extended version of Windows 10 you are using?  Win + S and type “winver” and hit enter.

      Thank you,


    • Hi

      I obviously did not explain clearly. I am accessing a tide-time website and just want to use the edge new tab / top site facility to create an icon that will take me there.
      The problem is that the URL is

      if I put this into a new topsite icon (the box with a + on it) it gets converted (all upper case change to lower) to
      http://www.ukho.gov.uk/easytide/easytide/showprediction.aspx?portid=0036a&predictionlength=7 and no longer works.

      Winver shows Version 2709 (OS Build 16299.371)
      Microsoft Edge 41.16299.371.0
      Microsoft EdgeHTML 16.16299

    • Same problem with the Australian BOM site (weather radar)
      URL for Sydney is:
      With idr in lower case, message received is: The page you requested was not found on this server
