I was working on my Drupal site and I added an existing block to another page through the DDBlock Module "configure block" "show block on specific pages" and then I get this message and now my block won't show up anywhere.

Schedule Live Meeting

Hello,

My website will connect clients with instructors. I need every instructor to set his own Calendar "Available / Unavailable".
The client will then click on an "Available" time to schedule a session with the instructor.

I don't need a full-blown LMS, just a simple mechanism to schedule sessions. Appreciate if someone can guide me to the suitable modules and (if possible) give me a quick walk-through.

Thanks!
