[getting more info] PHP, trouble changing exercises

  1. As I click on Save and Submit, it takes me to next lesson but the number of the lesson on the left bottom corner doesn’t change.

  2. Then when I clicked reload, it took me from lesson 4 to lesson 11.

  3. The third problem is, when I click at the bottom left corner to check the previous lessons, it just doesn’t work.

Can you still reproduce this problem Mario?
