For the past couple of weeks, it's taken multiple tries to get an upload to actually start. Very frustrating if you're trying to post some photos for someone in the ten minutes before you go off to work. Surely uploading a single zip file is not rocket science. But there it is, stuck at 0% right now.
The same happens to me. Also trying to post comments or delete them. Seems it's a problem related to the server "upload.pbase.com". Very... lazy indeed. Hope they will fix it.
