2.3.0 – critical error

Same error on multiple sites. Neither frontend nor backend are accessible any more. I did a rollback to version 2.2.5. Please fix ASAP. Same problem here. I renamed the plugin directory and was able to roll back to 2.2.5. The plugin is rolled back so I can have a better look. Can you tell me your php and wp version please? PHP8.3 WP: 6.9 (latest). PHP 7.4, WP 6.9 PHP7.4 WP: 6.9 (latest). Thank you! I will do detailed check I also had a critical error: (PHP 8.4, Latest WP Version) Error Details ============= An error of type E_ERROR was caused in line 44 of the file /nas/content/live/[SITE URL]/wp-content/plugins/email-encoder-bundle/core/class-email-encoder-bundle.php.

I hope you get a fix. thanks Just saying, this just happened to one of our sites. Might happen to others yet, I’m not sure they all auto update at the same time. Rollback worked, but I’ll keep an eye here for a fix announcement. Yep, happened to me too. Took down 3 sites. I removed the plugin because of the security issue listed in the changelog, didn’t seem like a great plan to roll back. Thank you for alerting us to the issue, we are working on a fix ASAP and will release something today Apologies for the previous release. Current is 2.3.4 A critical bug was introduced in the last version, and I apologise for any inconvenience it may have caused. This release is the current stable version and includes a full internal refactor. The focus of this update is improved code maintainability, security, and long-term reliability. Feature development will resume on top of this new foundation, with updates coming soon. Please note that the next major version will require PHP 8.0 or higher. If you are currently running PHP 7, upgrading is strongly recommended, as PHP 8 provides better performance, active security support, and long-term compatibility with modern WordPress plugins.
