Hi,
the media button for a WYSIWYG field in an acf block didnt work, so I looked into the console and found two seemingly ACF related errors –
#1 “Block names must contain namespace prefix…”
#2 ‘Uncaught TypeError”: Cannot read property ‘attributes’ of undefined.
While the custom acf block in question appears to work, including conditional display js for its fields, the media upload button on a WYSIWYG element does not.
This is in a freshly updated installation and merely *activating* ACF-Pro, even without registering the custom block, leads to the two errors above being displayed.
Any idea what could be the reason? Thanks!
