Conflict with the passster plugin

Hi, There is an issue: After adding Select Meta Key (created by the ACF plugin) （https://picshack.net/ib/ALfcaodTiN）, the search function cannot be used for a non-logged-in user; it will took long timeto search ( 70152ms ) and then show 502. It can work after login. I already deactivated all other plugins, but the problem persists. Removing the Select Meta Key or removing the Passster plugin ( https://wordpress.org/plugins/content-protector/ ) can resolve this issue. If use searchWP plugin, it can work well with the passster plugin.
