PHP 7.1 already powers all the sites we host since September last year and switching to PHP 7.3 will consolidate security and will bring performance improvements as well for your web properties hosted with Presslabs.
The development sites will be switched to PHP 7.3 today (June 11th) in order to allow you to test the full compatibility of your sites with the new version.
This maintenance window is scheduled for July 2nd
when production sites will be switched to PHP 7.3.
Please ensure that your dev team thoroughly tests everything on the dev site until then. This should give you enough time to check that all the plugins and themes are 100% compatible with PHP 7.3. If not, please contact your developer or the corresponding plugin developer, to implement the necessary fixes so that everything is fully functional before July 2nd.
