my Bot doesn't send posts to channels!

my channel name is https://telegram.me/artatrading
i’ve set username in the plugin as @artatrading
is it wrong?

My bot is username=@SpeakGifBot, I send messages from plugin but they don’t arrive to the subscribers.
The channel is https://telegram.me/SpeakGifBot.
I have not SSL, I registered at wptele.ga

What’s wring?

@amirhossein: did you set your bot as admin of the channel?

@fabio: do commands work? If you want to stream to the channel, add the bot ad admin and set the channel username in plugin options

Yes I set my bot as channel admin.

my php version is 5.6.
my channel name is https://telegram.me/artatrading
i’ve set username in the plugin as @artatrading
my bot is the admin of my channel.
But it’s still not working.

it doesn’t send messages to users or channels. it only sends to groups.
