Yesterday I had that problem too. After pressing Shift - F5 in google chrome, it did work :-)

I want to withdraw my left BTC on your website and i can't, " An internal error occurred. Please try again later. " . What that suppose to mean now ?

Please solve the error or this could be a very bad sign of exit scam.

I've been experiencing the same today and refreshing doesn't help. Dev, can you explain why we can't use this feature now?
