I transferred the site backup to my laptop for testing since the issue wasn't resolved on the live version. With the builder file you sent, I'm seeing this error.
I uninstalled SP Page Builder for testing and reinstalled it, but the issue and error are still the same.
I also updated Joomla to version 5.1.2.
A 500 error is also being displayed in the admin panel.
Compile Error: Cannot declare class SpPgaeBuilderBase, because the name is already in use
