Issue with wordpress 6.8

Same here.

In our case, the blocks causing problems are created using MB Blocks with the "Block registration without block.json" method described here: https://docs.metabox.io/extensions/mb-blocks/#block-registration-without-blockjson

Emiliano: in our code, we are only using the method without block.json, so we don't have any information whether it works with the other method using block.json.

We just thought we'd mention it, maybe it helps to narrow down the problem.

Not quite sure where the problem starts, but the register_block_type call in Block.php does not actually register the block, which can be confirmed via wp.blocks.getBlockTypes()

The updated 6.8 now has the additional method register_block_type_from_metadata to register blocks, but designed when the project uses block.json and not an array.

However for a MB block using block.json, this method also is not working.

This is a major issue for us as we use multiple custom blocks across all our websites. Can you advise when a patch might be available?

Hello,

This issue has been escalated to the development team, I will update you here when it is fixed. In the meantime, please downgrade the WP core to 6.7.2 to use the MB custom blocks.

Thank you.
