I found the problem.
Initially I named module as “Titus” and have javscript as “titus.js”.
I renamed like below and it worked.
“titus.js” to “Titus.js”
{
module: 'Titus',
position: 'middle_center',
header: 'Titus module',
config: {
text: 'Glory to God, Jesus and Holyspirit, all the time'
}
},
Thank you.
Regards,
Titus S.
