CMB SQLite Form is a lightweight yet powerful contact form solution designed for performance and privacy. Unlike traditional form plugins that clutter your main WordPress database, this plugin stores all submissions in a secure, local SQLite database.

<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.
