white screen when batch adding files

[Bob42]

Whenever I click on the "Batch Add Files" button, the page tries to load but then I just get a white screen. This never happened before on the server. I know that it takes a while to get the thing to load, but never have I encountered a white screen like this before. I am using the latest version of Coppermine.

If admin access is needed, let me know.

I tried exactly that, and I still get a blank screen when I click on the "Batch Add Files" link.

If you tried exactly that without succes, please, keep reading and you will find the next point: Asking for support on upload issues.

Do exactly what it says there.

Sorry about that.

Oh, great. The test user account doesn't have upload privileges. RTFM!. Play by the rules, start thinking for a moment and test the data you post before making us verify them for you. After all, it's you who wants help, not vice versa, so you better do your homework.
