Wordpress uses the fopen() function to get data from remote servers. 6scan security requires this to complete the registration and verification process.

If the allow_url_fopen option in php.ini is set to Off, the fopen() function will fail while getting remote data. Because the default value for this is "On", this can only happen if an administrator manually changed it. Since PHP verion 4.3.4, you can no longer override this value in an .htaccess file, using the ini_set() function, nor in a custom .user.ini file; therefore, you must change this value to "On" in the global php.ini (or httpd.conf) file.

If your server is running PHP as CGI/FastCGI, you can add the following lines to php.ini:

[PATH=/path/to/your/blog/directory/wp-content/plugins/6scan-protection]

allow_url_fopen = On

If your server is running PHP as an Apache module, the only currently available solution is to enable the allow_url_fopen option in the global php.ini.
