Fatal Error after Updte

After update 3.0.0, we get a fatal error on the site (error below). The whole site crashes with this error, but it does not occur if we don’t activate the plugin “Contact Form 7 – PayPal & Stripe Add-on Pro”. However, even if no other plugins are activated and the theme is set to default, we still get failure messages after searching.

We have rolled back to 2.5.3 for Better Search and everything works again.

Error Message:
