Theme Hook smart_trim not found

Hi thanks for your report. I have tried to replicate this but was unable to. Did you clear your cache? Usually when you introduce a new hook that needs to be done.

Hi, thanks for the reply. I used "drush cr" and restarted the server, that had no effect. After clearing the cache via the button the error disappeared. I am not sure if there should be differences, but it works as intented.
