I just found out the password configured in passwords.conf file has not been hashed. Any resolution to that.
I'm using old version - 1.3.4 and I can see the latest version as from now is 1.6.2 but can someone confirm this has been resolved before considering an update.
removing and reinstalling add-on fixed the problem. I can verify that was not permission issue over the files but whatever. If you find any other solution to the problem when facing it please post it here.
