My banner wont change

Question

So my problem is simple really and it may be an easy fix. But please help. I have recently changed important information about my minecraft server and I need to change the banner because the information is outdated. But everytime I upload the picture and save it stays the same on the server listing. Please help!

Answer 1

Try to click the "update server" button twice because sometimes the first time it bugs.

Make sure it also isn't too large and check the extension. It should be a JPG or PNG.
