Ok so I can now replicate fresh slave sites at will without any problems yay
no rules have been changed I am just specifying different table prefixes and defining the deployment directory which are both correct.
However I am having an issue when trying to replicate the master site , I just get taken to a blank page. Again no modifications to the rule have been made and the deployment directory has been created successfully and the mapping is correct.
JMS is fully up to date with the latest version installed
