When viewing a mobile page you may receive an error message:

"uh-oh I believe you made a mistake.

Did you type the URL? - if so, it's case sensitive!"

It is because the URL entered is invalid. More than likely the URL has been typed into a browser rather than clicking the link directly. Another case where this occurs is if in the text message the link is connected to the next word in the message instead of separated by a space.  

Links are unique and case sensitive. sWss is different to sWsS.

Also if typing a URL pay attention to lower case l (L) and upper case I (i) they look the same but are different.  

We strongly recommend clicking links instead of typing them into browsers.
