First tests with CP2 show that most plugins will no longer work properly. Since I’m just a single person without the commercial power there’s no point in continuing to focus on CP, so I’ll strive for WordPress compatibility where possible and exit this project.
I’m sorry, I made sure that everything works for CP1 to PhP8.1, but with the code base of WordPress 5.5+ there is then too much to customize which also cannot be reconciled with performance and security, so it doesn’t matter Sense. It just makes more sense to just concentrate on WP right away, keeping the focus on CP is too much effort for a small OpenSourcler
