File upload problem

I have added the allowed file types, but the upload is still blocked, what should I do? Is there a place in ASM that can limit the file upload extension? Is it necessary to modify it there?

You can find for details what is blocking, please check your support ID in the blocking response page.

Could you share the event logs for details?

My upload has been blocked, but there is no log!

First, did you set logging profile on VS?

Second, try to changes on transparent mode, if the result still go to blocking it shouldn't because asm policy.

Method not allowed - that looks like your server declined the file upload - rather than the ASM blocking it. The ASM response page does not (by default) reveal a reason why it was blocked.
