i really thank you for your advice.

OH!!! thank you so much! I followed your tips, and i resolved it…!
the problem is about access to the connection.
Thank you so, so much.
i’m deeply greatful to you for your help!
i hope to have a good day!!! :D

@Mykle1 oh i resolve it. your example is so helpful to me. i really thank you.
i was confused about that address number. .
but can i ask one more question?
what can i do for “ACCESS DENIED” in mm2? i resolve “NOT FOUND” problem but i have a “ACCESS DENIED” problem…

really thank you for your replying TT

@Mykle1 thanks to your reply, i tried it.
but this time, the error says “NOT FOUND 404”…
i have tried a lot. but every time says ‘NOT FOUND 404’.
if you know about it, could you tell me what to do…?
Thank you very much!
