This is the Easy Rule status page, mainly used to display errors when adding rules.
|
|
131
|
If you are seeing this, there apparently was not an error, and you navigated to the
|
|
132
|
page directly without telling it what to do.<br/><br/>
|
|
133
|
This page is meant to be called from the block/pass buttons on the Firewall Logs page, <a href="diag_logs_filter.php">Status > System Logs,
|
|
134
|
Firewall Tab</a>.
