Although no additional information has been provided by any source and I haven't been able to use a computer to observe operation of the plugin, in visual review of the changes made to the install program for ZC 1.5.4, it does appear that I missed the lower case m in $resultMmessage for the three new sections of code. Plugin is updated with that m added for each of the three cases.

@Corseter, could you confirm operation? (Again *assuming* that the files were downloaded from github for SBA Version 1.5.4)
