Helperid bought my attention back to this question.

That is a locked question! I CANNOT ANSWER IT!
Thanks for letting me know Asad, I appreciate that.
I did unlock it but it must have locked itself again automatically.
If it relocks again could you please let me know again. Thank you.
I think admin has now fixed this auto locking problem.
Thanks Admin :)
