Ronny Ko who has the same problem and also reported the problem a month ago, had not received any help at all on this problem until a week ago when I addressed it.
He reported today to me, the Problem is still present in version 4.0.5.
It is unfortunately still necessary to overwrite the article.php or correct it yourself.
components/com_sppagebuilder/helpers/article.php
line 53:
change !empty to !is_array
So I would like to ask you that you also forward the fix to the developers that the problem will be fixed in version 4.0.6.
