Don't do that (send an interrupt to a program that has turned off
echoing), or you're likely to get the result you just saw.

Well, when the pager program ("more" or "less", typically) started up,
it turned off echoing (since you don't need a "space" echoed when you
want to page down to the next page, for example). It's ready to turn
echoing back on upon normal termination, but you prevented that, by
sending it a signal instead.
>How do I fix this?
First, don't do that.
Once it's happened, there are various things you can do:
* An xterm-specific approach: hold the control key down & press the
middle mouse button; one of the actions you can select is a reset
(either soft, full, or with a "clear saved lines").
* A more general approach: enter ^Jstty sane^J (where "^J" is
control-J).
* An ambitious project: Make source changes to the various pagers so
they will turn echoing back on, even if they terminate as a result of
someone doing something unexpected, such as send a signal. (This is
unlikely to work for folks who use "kill -9" though....)

I'm a bit confused as to what error messages you're referring to in the
above. Error messages from what program(s)?
