I upgraded from Page Builder Pro 3 (running on Joomla 4) to Page Builder Pro 5 (after upgrade to Joomla 5).
Now I only see a blank page for every Page Builder site in the frontend,
When I try to access the backend of Page Builder Pro 5 I get the following message:
Cannot read properties of undefined (reading 'data')
What can I do to get Page Builder Pro working again?
Thanks in advance.
