MyBB Community Forums - Task to send email queue / Mass email not working

Hello, i'm running MyBB v1.8.27 since weeks and it seems that the tasks are not executing. I quoted the "send queue" and "mass" email but seems it is the same for other task. Launching the task manually seems ok but not possible to have a scheduled one to be executed.

MyBB forum is installed on O2Switch domain provider.

Thanks for your support.

Your footer template should have this at the bottom:

<!-- The following piece of code allows MyBB to run scheduled tasks. DO NOT REMOVE -->{$task_image}<!-- End task image code -->

Is this there?

I use the theme "myreponsive27" and seems to be inside (see screen shot below).

Can we have your URL?

sure : http://patatorz.com/forum/

Thanks a lot Matt

Sorry for the late come back as i was on business trip. The tasks are still not functionning based on schedule ; just work when i launch manually
In fact none of the tasks are executed according to the timer/schedule
