when trying to save changes after setting parameters, I get this error
Warning: mkdir() [function.mkdir]: Permission denied in /public_html/wp-content/plugins/private-wordpress-access-control-manager/lib/xfw_private.class.php on line 489
at line 489 I find a 'XFW_TMP_PATH' variable but I can't understand wich one is the folder I have to set as writable.
Anyway the plugin works and protects the site from public access.
Does anyone has some hint?
