<h1 align="center">Warning!</h1>
<p>Enabling debug mode on a public server may result in malicious clients retrieving sensitive data about your server and possibly gaining access to it. Do not enable debug mode on a public server, unless you understand the implications of your doing!</p>
<hr />
<p>Debug mode enables error reporting and prevents loading data from the cache (data is still written to the cache).
To enable debug mode, set in <code>config.ini.php</code>:</p>
<pre><code>enable_debug_mode = true
</code></pre>
<p>Allow only explicit ip addresses:</p>
<pre><code>debug_mode_whitelist[] = 127.0.0.1
debug_mode_whitelist[] = 192.168.1.10
</code></pre>
<p><em>Notice</em>:</p>
<ul>
<li>An empty file enables debug mode for anyone!</li>
<li>The bridge whitelist still applies! (debug mode does <strong>not</strong> enable all bridges)</li>
</ul>
<p>RSS-Bridge will give you a visual feedback when debug mode is enabled.</p>
<p>While debug mode is active, RSS-Bridge will write additional data to your servers <code>error.log</code>.</p>
<p>Debug mode is controlled by the static class <code>Debug</code>. It provides three core functions:</p>
<ul>
<li>
<code>Debug::isEnabled()</code>: Returns <code>true</code> if debug mode is enabled.</li>
<li>
<code>Debug::log($message)</code>: Adds a message to <code>error.log</code>. It takes one parameter, which can be anything.</li>
</ul>
<p>Example: <code>Debug::log('Hello World!');</code></p>
<p><strong>Notice</strong>: <code>Debug::log($message)</code> calls <code>Debug::isEnabled()</code> internally. You dont have to do that manually.</p>
