I am trying to get get the badge indicating that I have finished the lesson "For Loops in PHP". I have completed all the exercises but one, the "4. When to use for". The platform should reload the code from the previous exercise and the student is supposed only to click on Save and Submit to go forward. It seems that the platform has recorded an old mistake I made while coding the section 3. Even though I have corrected my mistake on section 3 and got the green check mark on it, for the section 4, no matter what I do (refresh page, reset code, delete everything and write again), I can't get the green check mark on it. Could anyone check for bugs here?
