Hi, on 2 websites (and perhaps more) we are having a problem with the searchfunction of WordPress.

I have taken these steps to see if this helps, but the problem is still there:
“We suggest to change the following Anti-Spam plugin settings:
– Set cookies to Off;
– Use Anti-Spam by CleanTalk JavaScript library to On.
Please also set the WP Rocket plugin up as we recommend in this article:?https://cleantalk.org/help/cleantalk-and-wp-rocket.
Do not forget to clear all website cache after every action.“

We also followed the instruction how to set CleanTalk together with WP-Rocket https://cleantalk.org/help/cleantalk-and-wp-rocket

I have to say that these steps are the default settings.

Do you have a suggestion how we can fix this?
