Thanks for your reply, krileon.
I already understood the point you made the first time, as i stated twice. Really.
Dont know, why you keep repeating mentioning the error logs: "I will look at them, at the weekend".
As i said. Then i probably will solve the error for myself.
I hoped, you could provide some "insider information", that saves much of the error-searching time (because of a Plesk-server,- uhm, you remember?) - but obviously: you couldn't.
I understood! I really do.
If there would be ANY questions, i surely will reply here again.
For now: thanks for reminding me of the error-logs.
