From some time after the ipb4 upgrade i get a lot of 404 from attachment files. after further inspection i have tracked the issue to not renamed files, they do exist with attach_file instead of attach_location.

 I want to make a script to walk core_attachments and rename files not renamed, since i do have both parameters. However there is one thing i can not understand

 

In filesystem i have stored: /uploads/monthly_07_2013/Some File.pdf.7886fc68f0a15895a1afcb6f463eb0cc

I have no idea where that hash comes from, and how to match efficently.

    "attach_ext": "pdf",
    "attach_file": "Some File.pdf",

}]

I'm having the exact same problem, however I did a test install for 4.1 in a sub directory of my 3.4 forums. Now all the attachments in my 3.4 forums don't work. Any idea on how to fix this?

Nevermind, I fixed this myself. For some reason the 4.1 install went back into my 3.4 install and moved all the .ipb files out of the /uploads folder so my 3.4 had all the attachments there but no attachment data for the posts. So all I did was copy everything back.
