Unfortunately I can’t reproduce this at the moment 🙁 * How does the upgrader access your WordPress install – does it use FTP or direct file system access? * Thread Starter [kpdesign](https://wordpress.org/support/users/kpdesign/) * (@kpdesign) * [16 years, 9 months ago](https://wordpress.org/support/topic/plugin-wordpress-beta-tester-php-error-when-upgrading-plugins/#post-1197117) * It uses direct file system access.
