When I go to upload a file using the webform, nothing happens. The uploader just sits there and spins. I get the following error in the console.

Version 2.9.4

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data[Learn More]
jquery.min.js:5:15991
TypeError: uploadCategory is null[Learn More]

That's not the content. Check into the Network tab instead, the answer of
the json request

Interesting, I'm getting the following:

Forbidden

You don't have permission to access /ws.php on this server.

Additionally, a 403 Forbidden error was encountered while trying to 
use an ErrorDocument to handle the request.

Yet, the permissions are set to 777.

Ok I am getting:

[prepare_directory] cannot create directory ".//mnt/volume_lon1_02/2018/08/28"

In my conf:

$conf['upload_dir'] = '/mnt/volume_lon1_02';

I am using a volume to store images. Is that a problem from using an absolute path, or is that a permissions issue?

Thanks for your help.

That's beyond my small knowledge of Linux and i don't know that part of
Piwigo, but could you use symlink instead of changing the setting?

I figured it out. For me, it was caused by the absolute path. It must be relative, as the comment above the setting says.

I needed to use:

$conf['upload_dir'] = '../../../mnt/volume_lon1_02';

Hm, I have a similar problem (piwigo 2.9.4). I see there's an attempt to upload files in upload/buffer : .part files are created with 0 length, but that's it. I see no error in logs.

Files are ~1-3MB, I verified I can upload files with small php script.

EDIT: I spawned a VM and installed it on vanilla system -- it works without problem. So probably something in my configuration is causing a problem. FYI: It's a FreeBSD 11.2, apache24/php71/mysql56 running inside jail.

PHP does have a permission to upload (tested by my small php script), so I'm obviously missing something ..

EDIT2: I'm updating the answer just in case somebody else has the same problem. In php.ini, among other things, I've upload_tmp_dir set to non-standard directory. For this reason I had to update open_basedir to include this dir in the path.
