Is there someone that know how to fix this error?
I don’t know what to do?

I belive it is Add-on Contact Form 7 – Mailpoet 3 plugin that is the problem.

Calling where_not_equal is deprecated and will be removed. Use MailPoetNewsletterSegmentSegmentsRepository and MailPoetEntitiesSegmentEntity instead.
