Hello WordPress Hosts!
The Core Development Team is requesting assistance with testing a new Rollback Feature in WordPress Core. As always, your testing contributions help keep the development process informed and are valuable to the WordPress Open Source Project! Thank you all in advance for participating in testing this feature!
This new feature offers the option to “rollback” to a previously installed version of plugins or themes that have thrown an error during a version update. Users may experience such an error as a WSOD (“white screen of death”), a visible PHP Error on the front-end or in another form during updates that can prevent a site from continuing to function without assistance from a Developer or Technical Support. This rollback feature will provide an option within WordPress Core itself for the user to set plugin and theme files back to the previously working version.
