Why is my the keyboard on my HTC not working?

[AC Question]

My HTC has stopped allowing me to use the keyboard. It won't even pull up as an option anywhere. Not on text, email, web browser, Facebook, nothing. Any suggestions? I can't even find it under my settings to adjust it.

Is this a third-party keyboard downloaded from the Play Store, or is it the stock keyboard that came with the phone?
