On November 15th - 17th 2023, the version corresponding to "Stable" in Atomic will change from 8.0 to 8.1. Your WordPress applications will automatically be upgraded to use PHP 8.1, which is still supported through November 25, 2024 and will no longer be receiving security updates after that time. Excluding any compatibility issues that may arise, the impact to website availability will be very brief - less than 2 minutes per app - while the version change is being applied.
As a proactive measure, we have scanned all apps and identified the ones that will have compatibility problems. Account Owners: We will be sending direct notifications to each Pagely Customer to highlight the apps failing our checks over the next 24-48 hours. Please take a moment to make sure the appropriate Collaborators on your account are enabled to receive Maintenance alerts in Atomic: https://support.pagely.com/hc/en-us/articles/360058630471-Configuring-Account-Activity-Alerts
As with any software upgrade, there is a chance of unforeseen compatibility problems that did not surface during our own testing. Our testing is designed to identify hard failures where the code cannot execute at all. Other, more subtle compatibility problems could still occur when the upgrade to PHP 8.1 is applied, where only certain components are not functioning correctly, or new non-fatal warning messages appear. If you experience these kinds of issues after the upgrade, please contact Pagely Support for assistance: https://support.pagely.com/hc/en-us/articles/114094215332-Contacting-Support
