Hey,
using T4 Page builder and is seems there are some issue regarding the back-end and working of the builder.
First
UI thing; you have to toggle the Joomla menu to show the login T4 screen
Second;
right now I am not able to use and create New Pages and not able to Import example pages from the menu. Creating new categories is possible.
Installed all updated all versions and even installed it from blank again. Still no results.
Using Joomla! Version 4.0.1
PHP Version 7.3.29
Any known same issues?
