4.0.0 causes unspecified fatal error
-
Multiple sites that I manage with the latest version of WordPress went offline upon updating to WPO 4.0.0. The sites have different themes, different plugins, different purposes. In every case, WPO was installed (and on the sites without WPO, all is well).
Trying to (re) activate the plugin results in the message: “Plugin could not be activated because it triggered a?fatal error.”
Linux host with latest PHP 8.4.3 release.

Prior log entries were more than a month old.
