Got the following messages when I try to enable config:

Cannot start transaction

please post the output of the events reported by the command 'errdump' run via CLI. It may provide more info about the failure.
That is most likley because this switch is trying to obtain an ACA (Acquire Change Authorisation) from another switch which it does not get. Most common cause it the other switch already has a transaction lock active. You will need to check the fabriclog or portlogdump to check out which switch this is.
If you figured that out yo need to abort the transaction on that switch and try again.
