Our plugin works out-of-the-box and doesn't require any special setup on your hosting and it won't break the features of other third-party plugins.
Although the ACF Views plugin works well with any default hosting setup, some hosting providers may have some settings that they consider as default.
Websites hosted on a Linux server with the opcache php module enabled, with the setting to remove comments from code (which is not default behaviour) will experience issues with the View and/or Card user interface.
Contact you hosting provider and ask support to disable this option on your account.
Do it yourself by opening your php.ini file and modifying the line with opcache.save_comments changing the value to "1".
Why does this happen and why are comments in code critical? Some libraries use comments to classes and class fields (PHPDoc) to keep meta information. A common example is PHP Doctrine. Our plugin also relies on PHPDoc
