Hello

we have observed very strange behavior with some users. When downloading a PDF document, the downloaded file is not shown in the downloads folder.

• Only PDFs aren't being downloaded; other file types work fine.
• The server response has status 200; I see the request in Chrome Developer Tools, which confirms that the server successfully responds to the request. However, the PDF file still doesn't appear in the downloads folder.
• Other file types, like Word documents, for example, work fine in Chrome.
• Downloads work for all file types in Edge.
• For some users, it is a temporary problem and resolves itself after some time, but may appear again, it comes and goes.
• Problem appears only on K2 Sites.

We weren't able to find out what is causing this behavior we fix it by renaming the user profile,
 

1. Backup Bookmarks (take note of plugins)
2. Close Chrome
3. Rename C:\Users\%username%\AppData\Local\Google\Chrome\User Data to C:\Users\%username%\AppData\Local\Google\Chrome\User Data - BackUp
4. Restart Chrome and import bookmarks (install plugins)

If anyone knows what causes this strange behavior, please post it here.

thanks
