We run OJS with a webhosting provider, therefore we have only access to the server with FTP. We cannot find out the name of the user who runs the PHP scripts and we cannot chown the files to him. (But we do have the files directory above the web directory.) Updating to or installing OJS 3 did not work (as discussed here), possibly because of the wrong file permissions. PHP is set to Fast-CGI. Before we try to install OJS3 again, I want to know:
Is it true that if I set permissions of config.inc.php, the files dir, ./cache/, ./public/, /plugins/ and of /locale/ to 777 and the problem persists, then I know that lack of permissions is not the cause of the problem?
