Error when getting backup

[AriyanPayamak]

After updating directadmin to new version,and add CustomBuild 2.01 to DA console , unfortunately some parts have been disabled after the system update.
For example, when I want to delete messages, I will get to the following error page when I delete the system messages.

Or the same error occurs when I want to back up a user.

I don't know the error where is came from ?
How can I view the log or error? And how fix this problem?

Hi again i fix this problem ,

i dont no ! why max Request /Upload Size why 200 B
DA Console did not have access to change size .
i set from ssh

/usr/local/directadmin/conf/directadmin.conf

Set size : 128M

The problem was solved .
Thank you very much

Just checked 2 new updated boxes and both of them are set standard to 10 MB upload size, something went wrong from your side I assume
