Search archive is restricted for logged off users

Hello,

My site is a publicly accessible site but some parts are restricted. The site uses the standard WP search function (After a search command the URL is <domain.extenstion/?s=<term>). The search result archive page is built using the WP Bakery page builder. Somehow the page shows the restricted message for logged off users. I’d like this to be public. The search results (custom post type) should be visible for everybody but some posts are restricted.

The search page and the posts of this custom post type are not restricted by default. I can’t find any setting to remove the restriction from the search results page. Is there any option for this?

Thanks in advance for any reply.
