File upload failed, ensure permissions are writeable (777) on the upload directory

[MAXOUXAX]

I get this error every time I try to upload a file from ShareX, and even after redefining the permissions, the error still appears. Here are the two commands I ran: sudo chown -R www-data:www-data release/ sudo chmod -R 755 release/

Can you make sure that the permissions are writable on your file upload folder? (Probably release/u/)

I started having the same issue the other day.

Make sure there is storage space left on your root partition of your web server. This is where files are stored temporarily before being saved to disk in your uploads folder, I believe.

Yes, all folders and files have the right permissions.

Yes, there is enough storage space and inodes available to create new files.

I am having the exact same issue on Ubuntu 20.04. I have plenty of storage space left and I have the exact set of permissions as @MAXOUXAX

I am trying to re-create the issue but it seems completely random.

I would check you're not hitting max upload size, try a really small file? See: https://github.com/JoeGandy/ShareX-Custom-Upload/issues/8

[JoeGandy]

We should probbably look into adding errors and checking them against max upload size limits in php to make the errors more clear

Just tried with a 1 Ko text file, same issue. The problem with this error is that it is triggered by a PHP method, which can fail for many reasons. However I don't see what is bothering PHP, the permissions are set correctly, there is enough free disk space and the upload limit is not exceeded.

[JoeGandy]

Yeah you're absolutely right on the error being super generic, Any more info in the php error logs?

[MAXOUXAX]

There are no errors in the PHP error logs, however I just noticed that an error is sent in the nginx logs.

Ok that gives us some more to go off, how are you uploading the file, through sharex? through the web inteface?

It seems to think you haven't passed a file into the POST script and $_FILES['fileupload'] is empty

I'm trying to upload files through ShareX - upload is working fine with the web interface.

[MAXOUXAX]

Alright then, I don't really know how it happened, but somehow my ShareX custom uploader got messed up and fileupload became d. Problem solved!

[JoeGandy]

Awesome, Yeah i was just about to suggest that, Did you use the auto config generator for shareX it could be an issue in that?

I was using the configuration generated from the website, and it worked fine, but I guess I accidentally changed a field at some point and it broke the uploader?
