Cannot click on the button "Save" or "Update"

[DeepDapy]

I'm new to minehut and created a server. I checked through all the settings. I want to change the settings at the two last squares of "Appearance" tab, which are "Server Visibility" and and "Server MOTD". But I cannot click on the button "Update" or "Save". I mean when I click on them, they are green, not turning into grey. My mouse icon is also not turning into a hand icon which means it's not being clicked, even if I put my mouse AT the buttons. I don't know why. Other tabs also have the same problem - the two last squares cannot be saved. Can anyone tell me how to fix this please. Any help would be valuable. Thanks in advance
