I have the same problem!!! i installed my ossn in my host, but the images is broken.

i made everything that you said but it don't running

You know how i could repaired this problem?

@Zet Man,

I think the issue with his installation is its missing back slash from end of path. Even its considered as directory but when writing files ossn_data acts as file in his case

So correct path is

$Ossn->userdata = '/var/www/ossn_data/';

@Jessie Abernathy
You should try to change path to above mentioned

Okay,

[28-Oct-2017 13:55:03 America/LosAngeles] PHP WARNING: 2017-10-28 13:55:03 (PDT): "mkdir(): Permission denied" in file /var/www/html/ossn/classes/OssnFile.php (line 207)

is telling us that Ossn fails to create a subdirectory in your data directory.
Most likely you created /var/www/ossn_data as root, and apache - running under a different user id - has no permission to create files and directories. As a result your images can't be saved.

So, let's retrieve the owner of apache ... from your shell run the command

ps aux | grep apache

You'll get several lines of running apache processes with the owner shown in column 1

Ignore the first line which is the master process started by root. The owner of interest is shown on the following lines, by default this should be www-data

Assuming it IS www-data, your next commands will be

chown www-data:www-data /var/www/ossn_data

and

chmod 755 /var/www/ossn_data

Having changed the owner and permission of /var/www/ossn_data this way Ossn should be able to store its data now.

I apologize for the lack of information... I didn't even know how to enable OSSN's error reporting or where the logs are kept... I am brand new to all of this I'm sorry. I found my ossn.config.site.php file and found out how to enable the error reporting here are the two files -->

Also if i remember, you have wrong path for ossn_data directory? can you list your ossn.config.site.php here?

> I don't know if they aren't uploading because of permissions or some other error like I said

Okay, and that's why it is a good idea to enable Ossn's error reporting and provide your log file, the ossninfo page, etc.
(I had asked you already several times to follow the instructions outlined in 'How to report a bug' to no avail)
