I'm just checking to see if is is an issue with my computer or the PHP lesson.
I just finished the 4th part of lesson 1.
On just about every part of this lesson so far, I keep getting a popup that says "error" and instructs that I refresh my browser before I even finish typing the code. Then I have to refresh the page and start all over again. It always lets me finish typing the second time, but this is starting to get frustrating. Is this an issue with the lesson or something that is just happening to me?
