I am facing a persistent database connection issue on my website (parkircoffesedayu.free.nf), and I hope someone can help or check my account configuration.
Your account configuration is fine, but you’re using the wrong credentials.
Our account usernames start with if0, not jika0. The difference is probably caused by a translation feature in your browser that sees the if word and translates it to Indonesian.
For this, and many other reasons, I strongly recommend to use the members area over the control panel. It is possible to tell browsers not to translate specific data, and the members area has most credential fields tagged for that. The control panel is not, so your browser naively modifies the settings shown.
