After upgrading to HS4 on my SEL linux machine I cannot get HSBuddy to run. The error is INFO: plugin start is pending. I have searched for whatever I can find on this and so far nothing has worked. User and password are the same in HS4 as and with that being the local user. I have removed comment marks in folders you've mentioned in other posts. I have installed HS4 on an old Windows PC I have and things work. Seems to be this Linux device.
