Hi David,
You can see the issue here: https://www.liedjesfabriek.nl/blog/ I’ve deactivated the code now.
GP 3.2.4 + GP Prem. 2.2.1 + GB 1.6.0 + GB Pro 1.4.0 are used.
The issue occurs (for example) when there is an image in the left column and text in the right column.
So ‘cards’ that are linked to single posts in which the text is not the first element in the first container (of a grid), don’t show an excerpt.
If I activate the code again, than the excerpts are shown.
In the block editor (backend) it says “Geen berichtsamenvatting”, which is Dutch for “No post excerpt”.
