Problem with attachments
 

Hi
Since I did the update 4.2, when I click on an attachment, I have a blank page (popup) and it is impossible to add attachments.
The source code for the page is not empty but nothing appears.
The problem occurs with the default style, but also with other style.
Someone has an idea and better solution? Thank you very much :)

Here is a page from the manual about troubleshooting blank or 'white' pages: https://www.vbulletin.com/docs/html/blank_pages

Thanks, i will serach in this direction :)
