How can I show text message content on locked screen?

[AC Question]

I have a galaxy s6 active and all of a sudden my text messages do not show the preview on the locked screen anymore.

It used to show the senders name with one line of the text and now it just shows
"Messages
New Message"

I didnt change any settings and i double checked and it all looks like it should be properly displayed

Double check your settings again. Then power your device off. Boot into recovery with pressing and holding vol up, home, and power all together at the same time. Then go down to wipe system cache and use power button to select it then choose yes to clear it. This will note not wipe any personal data.
