Hi,
Installed the new SPB 4 alpha2 on a clean Joomla 4.0.5 version, that went fine without any errors or messages. But when i tried to place my account information in the "License & Update" page, it won't save. Same happens when i try to make a page on the front-end, it won't save.
The error that google gives is:
Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0
