Hello,
  I installed the following application  (DP45) PM Viewer 4.0.7  but when I view users' private messages, I can't download the files they've exchanged

Do not download the files the users had exchanged and the problem will stop bother you.

Vask0 у нас запрещено использовать сторонние сервисы для публикации фотографий. Фото нужно загружать в редактор.

I want to download the file from the users, and when I do it gives me the following error...

 

Sorry, there is a problem
