Hi, I tried it, but it's no work.
I also remove the key from system_settings pkurg_page_builder_settings and resave the settings, but the PageBuilder didnt start, and in the Static Page section, there is classic OcotberCms editor.
Octobercms developers sometimes make such changes in new versions that they break the work of plugins. To work correctly with the new versions of October CMS, you need to make changes to the plugins. Which I did.
I didn't change the plugin version, just made the necessary changes.
In order for them to take effect, you had to reinstall the plugin.
