Error in database

sorry but for some time now if I want to create a new message I get:
Fatal Error: Unable to create message, did you forget to update the database?
can you help ?
thank s

@isct23 What is the background to this? When did you last successfully create a campaign and what might have changed since then?

What version of php are you using?

You can try enabling error reporting by modifying this line in file admin/init.php
