Motorola Moto G — Gmail problem

Hi everyone - when trying to send an email from my phone I cannot write it as the keyboard no longer appears. It does send emails if I choose to use the voice recognition system but I don't want this feature at all. This has only happened for the last week or so and i have to send emails on the computer which is not always convenient. Has anyone got a solution for this please. I have rooted the phone to use other apps but it was working perfectly after this was done. Thanks in anticipation,
Stuart.
