Ok, now everything seems to work better. The comment function might have caused a problem. I am going to add the status tools to here.
This kind of problem reminds me of a comment from my colleague, who is an engineer, that computer never works wrong, if it seems there is a problem on it, that's your fault. Or something from space causes it.
I dare to say it is not my fault, but I'm happy to succeed to debug. Yes!
