Hi all, I need some help regarding an issue I have. Kanboard works like a charm, however I can’t upload files to a task. What happens is that the progress bar sticks to 100% and I never get the message “All files have been uploaded successfully.” In short the progress bar stays at 100% forever. The only thing I can do is cancel the action. When I enable debugging I only get the cryptical entry in the logging: [2019-05-20 08:52:59] [debug] Kanboard\Core\Controller\Runner::executeController =\> \Kanboard\Controller\TaskFileController::save [2019-05-20 08:52:59] [error] File not uploaded: 6 I checked all the settings (like php.ini), but can’t find anything wrong. Does anyone has some tips how to troubleshoot this or has the answer? I would really appreciate some help. Kanboard is installed on windows 2016 with mysql as database and PHP7.2.7. Thanks in advance, Allan ---

Permissions to data folder, maybe? ---

Thx for your reply. The webserver user (IUSR) has modify rights on the “data” folder of kanboard. So that should be correct. The extra challenge I have is that I can’t access the production system directly. I have a test system where I have full control. On this system I can’t reproduce the behavior. If I set incorrect file permissions on the test system at least I get the message “Unable to upload files”: ![UploadWrongPermissions](https://global.discourse-cdn.com/free1/uploads/kanboard1/original/1X/738a986aac82672ffc504c3d9272574654e3ec19.png) and not a progress bar sticking to 100% where nothing happens. Hope I make myself clear here and someone can help me out. ---

permissions is really the only thing that would give you 100% and then not go any further. If it was server upload limit, it wouldn’t give you 100%. If you look at the TaskFileController-\>save(); method, you will notice, the only error message you could get there is “Unable to upload files, check the permissions of your data folder”, and that is where it is dying. > > You may not have flash enabled to prevent the second error from showing, would be an explanation as to why you aren’t getting it. 9 to 10 odds, permission issue. ---

Although, your’s is actually failing here, odds 5/10 permissions now…just not to the data folder: `[error] File not uploaded: 6` > Error #6 is tmp folder issue: [https://www.php.net/manual/en/features.file-upload.errors.php](https://www.php.net/manual/en/features.file-upload.errors.php) - is your upload tmp folder set in php.ini? - permissions to that folder? - does the folder even exist? ---

thx again for your reply, this is helping a lot to troubleshoot the issue. The tmp folder for uploading files is not set: ![phptempsetting](https://global.discourse-cdn.com/free1/uploads/kanboard1/original/1X/4a8cee738b15f53ed66e6310b4a8e29a009d7de6.png) assuming “upload\_tmp\_dir” is the correct setting. And if I try to reproduce the error on the working test system that fails. In other words I set the upload\_tmp\_dir to a location where the webserver user has no rights. Still I can upload files. Guess this tmp settings has nothing to do with this issue. Also I compared all the PHP settings of the working and non-working system. The only useful difference I see is the path environment setting of PHP. This isnt set in the non working system. Any other suggestions? ---

The thing is, error value 6. Its telling you what the issue is. I promise it’s not lying. If it’s not set in php.ini, I think it just uses /temp on the base directory, and if you don’t have write access, error value 6. ---

Thx for narrowing this problem. I will look further into what tmp folder exactly it uses. I’ll give a notice when its finally solved. ---

It’s clear for me now and I could reproduce the behavior. With the help of process monitor I could log the write actions. The following: - if “upload\_tmp\_dir” in php.ini is not set the system will use the default tmp folder which is c:\windows\temp - if “upload\_tmp\_dir” is set it will use this folder. But when the webserver has no right to this folder it uses the default tmp folder - if both tmp folders are not writable I’ll get the permission error I’m sure I can solve this now on the production system. Thanks again for your help!
