user2734: I successfully setup a testnet node over the weekend, all was running fine - I was able to create wallets and perform transactions etc.
However when I try to run the node today I am getting some errors, I haven't changed any config, I literally just turned the machine off and when I booted back up it didn't work (see error at the bottom)
I have downloaded the latest config files, I also deleted some data from the immutable folder in /db  - it synced up again but then gave the same error
I hope someone can help, many thanks in advance.

user1142: Today the Alonzo hardfork was done on the Testnet, you should update your cardano-node and cardano-cli to version 1.29.0.
