Can't access my messages

Hi, is anyone having trouble accessing their messages? The problem I’m having is that when I press the message ‘button’ it automatically activates the ‘search’ button at the same time, it’s like as if no matter what tag you press down the right hand side of the screen it always sets off the search. I have tried shutting down my phone, laptop, logging out etc but nothing works. Any ideas chaps?
Richy.
