Now, It's time to get technical!

Do what the image says to get to the source of the problem.

If you do the thing in the image and it still doesn't work, try left-clicking and inspecting the results.

If it still doesn't work, try typing "view-source:" before "https..." in the URL.

If you are on mobile, there are some websites that will allow you to view it.
