Hi everybody, I have some problems with uploading files to cleanfiles. Each time when i will upload a file, this file failed to upload and i get the error message "Invalid token". This happen when i upload a file with the single file button. If i try to upload a file with the drag and drop function the blue upload bar will fill to the end but it stays there for ever. I try to upload my files with different browsers (IE, Chrome, Firefox), i also try clearing my cookies without any results. At last i have Googled my error also without any result. What can be the problem? Is there any one else with the same problem?
