error common one but HELP PLZ

it keeps comming up with the server check error the one thats like you are ether offline or ms is going thro a server check viset the websight for more info and i know my internet is fine and its been comming up with that error for 2 days now

If it says its in a server check the server is offline. But a few minutes ago the server was online so and yesterday it was online too. Maybe you try it at the wrong time. Or don't have the good files (maybe).
