The best course of action would be to enable Broadcast debug to file mode, broadcast the post that uses the blocks, and then send me the debug text to read through: [email protected]
Thanks for the prompt response. I will broadcast the reusable blocks & then the post again to a child site, after enabling the debug to file mode and email you shortly.
I was able to get it working!
There was an open session error on our network that needed to be resolved by closing the sessions properly. Immediately after that threw an ajax error on the reusable blocks management page. I was able to rebroadcast, in addition to doubling our PHP memory, which when broadcasting to 13 subsites still caused some memory issues, we will just batch them in smaller groups in the future when we move to PROD.
Thanks for pointing me to the debugging options.
Forgot to mark as resolved!
