<h3>Configuration</h3>
<h4>Global vs. Form Settings</h4>
The plugin uses a smart inheritance system: 
1. Global Settings: Define the default behavior for ALL forms (e.g., your SMTP server, default styling, admin email). 
2. Form Settings: When editing a specific form, you can toggle “Override Global Settings” on any section to customize it just for that form.
<h4>Setting up Bot Protection</h4>
<ol>
<li>Go to Global Settings > Bot Protection.</li>
<li>Enable Honeypot (recommended).</li>
<li>Enable Time Validation (e.g., set to 3 seconds).</li>
<li>(Optional) Enable CAPTCHA for stricter forms.</li>
</ol>
<h4>Configuring Email Sending</h4>
You can choose how emails are sent: 
* WordPress Default: Uses your server’s standard PHP <code>mail()</code> function. 
* Custom SMTP: Go to Notifications > Outgoing Server to configure a specific SMTP server (Gmail, SendGrid, etc.) for reliable delivery.

This plug-in stores the Page HTML / REST json data that dynamic WordPress blog has been generated as a output cache by SQLite. After the cache, it can respond to the request to the ultra-high speed by using a cache without starting the WordPress of processing. 
In the case of REST API, caching is also performed for internal requests made by logged-in block editors, etc.
<h4>Simple Setup</h4>
<ul>
<li>Enable the cache, select the cache expiration.</li>
</ul>
<h4>Cache exclusion condition</h4>
Pages
<ul>
<li>Login user</li>
<li>Home/Front_page, Fixed Page, Post, Custom Post and WP embedded content card only. Other than this page does not cache.</li>
<li>Page you want to exclude from the cache, you can specify from the edit screen of the meta box.</li>
<li>Pages that are protected by a password does not cache.</li>
<li>PHP error (excluding E_NOTICE, E_STRICT, E_DEPRECATED) occurred page does not cache.</li>
</ul>
REST API
<ul>
<li>REST method is other than GET or OPTIONS</li>
<li>REST no data response</li>
<li>REST route endpoint you want to exclude from the cache, you can specify from the edit screen of the meta box.</li>
<li>REST error response</li>
<li>PHP error (excluding E_NOTICE, E_STRICT, E_DEPRECATED) occurred page does not cache.</li>
</ul>
<h4>Cache Clear</h4>
<ul>
<li>Clear the cache of automatically corresponding post in the articles and editing changes and the like of the comment.</li>
<li>The cache is a plugins and widgets such as a change is not clear. If you make these configuration changes, etc., should be cleared to use “Cache Clear” button.</li>
</ul>
<h4>Log</h4>
<ul>
<li>When you activate the log, you can easily check the behavior and execution time of the cache. (slower only a little)</li>
<li>SQLite database keeps logs for one week.</li>
</ul>
<h4>To further speed-up</h4>
Page cache processing of this plugin is processing in PHP and SQLite. 
You can also use a faster Expert mode. To use Expert mode you need to edit ‘php.ini’ and add auto_prepend_file. 
Or you can edit the .htaccess file and use mod_deflate and mod_expires or mod_pagespeed etc to make it faster. 
If you do .htaccess edit, edit from the well studied. Do not forget that you back up your .htaccess file.
<a href="https://wordpress.org/plugins/plugin-load-filter/" rel="ugc">plugin load filter</a> is also recommended for speed you do not use the cache.
For more detailed information, there is an introduction page.
