Meantime, this won’t affect how your site because it’s only a warning. * Plugin Author [Marcus](https://wordpress.org/support/users/msykes/) * (@msykes) * [8 years, 10 months ago](https://wordpress.org/support/topic/php-7-compatibility-193/#post-9340706) * This will be fixed in the next update, but it shouldn’t have any effect on the functionality of the plugin. Many are using PHP 7 (including myself) without issue, you can go ahead and upgrade. * [ChristiaanBoland](https://wordpress.org/support/users/christiaanboland/) * (@christiaanboland) * [8 years, 9 months ago](https://wordpress.org/support/topic/php-7-compatibility-193/#post-9446430) * Hey, * I’m running this website (ngm1780.nl) with WP4.8.1, theme Choices by Kriesi under PHP 5.6.31. Using my test website I’ve tried to run it under PHP7, as the PHP Compatibility Checker tells me there are no errors. Indeed there is the warning as discussed here above. The website seemed to run OK, but that was misleading: When I jump to an event-page, a blank page turns up. When in the admin, Events shows the normal header up to and including the heading of the list itself, but no listing of events. The number of Future Events (9), just like All Events ( 40) is correctly displayed. Somehow the list of events fails to display, like the CONTENT in the events page. I’m puzzled where I should look for a clue to solve this problem. * Christiaan * [ChristiaanBoland](https://wordpress.org/support/users/christiaanboland/) * (@christiaanboland) * [8 years, 9 months ago](https://wordpress.org/support/topic/php-7-compatibility-193/#post-9467109) * I’ve now made a small test: I also added a Portfolio item. In the Dashboard, it turns up as required on the page [https://mywebsite.nl/wp-admin/edit.php?post_type=portfolio](https://mywebsite.nl/wp-admin/edit.php?post_type=portfolio) * But when I find the Events on page [https://mywebsite.nl/wp-admin/edit.php?post_type=event](https://mywebsite.nl/wp-admin/edit.php?post_type=event), the list is empty, although it shows: All (42) | Published (41) Search Events:
