Hi there

today 27/6/24 @ 10.15am NZST I upgraded to the latest plugin updates and now getting a weird blocks javascript error;

TypeError: Cannot read properties of undefined (reading ‘length’)

This happens when trying to using the block builder in a new post or page, have tried with Chrome, Edge, Opera and tried switching PHP to 8.1 (was 8.2) and 8.3. Same issue.

To isolate the issue, I cleared cache everywhere, deactivated all plugins etc, followed all steps, even reinstalled WP. I found the issue to be with the kadence blocks or blocks pro – I was not able to find the root cause – appears to be a react issue. But when deactivated, the issue no longer occurs. Obviously inconvenient not to be able to use blocks pro so please advise fix.
