Can't upload my score!

I've been working on a composition of mine for months and now ı cannot upload my score/task, whenever ı try to upload it; it's loading, loading , loading and nothing more. After a day, ı always see this "no page found" warning. I even tried to create another account and also ı've tried to copy and paste all the notes to a new empty page. Still can't upload. I don't if it's website- wide isue but hope you can find a solution for my problem, thank you...
