WP 5.8.1 issues with PHP 7 (blank edit page). Had to roll back to 5.7.3

  • Looks like WordPress 5.8.1 causes issues for sites on PHP 7. I’ve tried our site on two separate servers, one running PHP 7.4.24, and the other 7.2.34. Both have same issue with WordPress 5.8.1:

    Blank white page when adding or editing pages.

    I tried everything: Deactivavted ALL plugins and reverted to Twenty Twenty theme. Nothing worked except rolling back to WordPress 5.7.3, which solves the issue. A painful waste of time. I won’t be updating WP in a hurry next time.

    Debug log file on blank white pages reports the following:

    [13-Oct-2021 09:39:03 UTC] PHP Notice: map_meta_cap was called incorrectly. The post type shop_order is not registered, so it may not be reliable to check the capability “edit_post” against a post of that type.

    To be clear, this post isn’t a “help my site is broken”, it’s a “WordPress 5.7.3 works, and 5.8.1 does not.”

  • WordPress 5.7 and 5.8 are both compatible with PHP 7.2 and PHP 7.4. If you’re experiencing issues a plugin is likely the culprit. Note that plugins do not necessarily share the same requirements as WordPress itself. I can see from the error message that you’re using WooCommerce, which requires PHP 7.3, for example. Do you still experience the issue when plugins are deactivated?

    @jakept Once again:

    I DEACTIVATED ALL PLUGINS. All means all. Including WooCommerce. I also reverted to twenty twenty theme.

    I also tried on two separate server environments, one an Amazon instance, the other a Cpanel account on shared host. Exactly the same result. Blank white page when adding/editing pages. Reverting to WordPress 5.7.3 resolves the issue.
