0 uploads were successful.

Have you checked your disk usage? Do you have available space?

enable debug_mode in coppermine config (with notices_display off) for everyone, then go to "groups" and set "method for uploading files" to "Single file uploads only" for all relevant groups. Then try again uploading - this time, you should get a more detailed error message what actually goes wrong. Post your error message (not the debug output) here - if it doesn't mean anything to you, post a link and non-admin test user account with upload privileges as well.
