Hi @bcworkz, thank you for your answer.
The link I attached in the previous post was the original gallery that was not yet converted. After conversion, a previous gallery post looks like this:
https://bernfred.dimjon.de/?p=8
The HTML code view is:
<ul class=”wp-block-gallery columns-3 is-cropped”>
but it’s empty, with no reference to the original images.
I’m really puzzled by this, as the gallery is recognized correctly before the conversion to blocks. The original HTML before conversion is:
<div class=”gallery gallery-columns-3″>
Yes, not converting to blocks is of course an option, I still would like to do it if somehow possible, in order to use more advanced gallery blocks afterwords.
Thank you very much for your help and further ideas,
Michael.
