please update wpdm advanced access control add-on.
It has updated from 3.2.9 to 3.3.0, but unfortunately it does not help.
I have also noticed that there are two advanced access control plugins: 3.0.4 and 3.3.0. Deactivated the 3.0.4, but it also does not help. Deactivating 3.3.0 and activating 3.0.4 causes wpdm_my_downloads to be uninterpreted.
