Installing WPsigner

This guide covers both editions. Pick your path first, then follow the matching steps.

Edition	Install from	Details
Lite (free)	WordPress admin → Plugins → Add New, or wordpress.org	PDF, max 2 signers — Lite vs Pro
Pro	Account Portal ZIP	Full feature set

Do not run both plugins active

When Pro is active, Lite does not load. Keep one edition active. Upgrading to Pro keeps your existing Lite documents (same wps_* tables).

Before You Begin

Ensure your server meets the system requirements:

• WordPress 5.8 or higher
• PHP 7.4 or higher
• OpenSSL extension enabled
• 128MB memory limit minimum

Install WPsigner Pro

Method 1: Upload via WordPress Admin (Recommended)

This is the easiest method for most Pro customers.

Step 1: Download the Plugin

1. Log in to your WPsigner Account Portal
2. Open the Downloads tab for the main WPsigner plugin
3. For official addons (for example Smart Signing Forms), use the Addons tab instead
4. Click Download to get the latest ZIP file
5. Save the file to your computer (do not unzip it)

See Account Portal and Addons Overview for addon downloads.

Step 2: Upload to WordPress

1. Log in to your WordPress admin dashboard
2. Navigate to Plugins → Add New
3. Click the Upload Plugin button at the top
4. Click Choose File and select the Pro ZIP file
5. Click Install Now
6. Wait for the upload and installation to complete

Step 3: Activate the Plugin

2. You’ll be redirected to the WPsigner dashboard
3. Follow the welcome wizard to complete initial setup

If Lite was installed earlier, deactivate or remove Lite after Pro activates successfully. Your documents remain.

Method 2: FTP/SFTP Upload

Use this method if you have server access or the admin upload fails.

Step 1: Extract the Plugin

1. Download the Pro ZIP from your account
2. Extract/unzip the file on your computer
3. You should have a folder for the Pro plugin (typically insigner or as documented in your download)

Step 2: Connect via FTP

1. Open your FTP client (FileZilla, Cyberduck, etc.)
2. Connect to your server using your FTP credentials
3. Navigate to /wp-content/plugins/

Step 3: Upload the Folder

1. Upload the entire Pro plugin folder (for example insigner) to /wp-content/plugins/
2. Wait for all files to transfer (this may take a few minutes)
3. Verify the main plugin file is present inside that folder (for example insigner.php)

Step 4: Activate in WordPress

1. Log in to WordPress admin
2. Go to Plugins → Installed Plugins
3. Find WPsigner (Pro) in the list
4. Click Activate
5. If Lite is also installed, deactivate Lite so only Pro runs

Method 3: WP-CLI (Advanced)

For developers and automated deployments:

# Navigate to WordPress directory
cd /path/to/wordpress

# Install from local zip file
wp plugin install /path/to/wpsigner.zip --activate

# Or if you have direct download URL
wp plugin install https://wpsigner.com/download/wpsigner.zip --activate

Post-Installation Setup

After activating WPsigner, complete these essential configuration steps:

1. Configure Digital ID

Your Digital ID is required for signing documents with legal validity.

1. Go to WPsigner → More → Digital ID
2. Choose between:
   • Generate Self-Signed: Quick setup for testing or internal use
   • Upload Certificate: Use your own .p12/.pfx certificate from a Certificate Authority

Tip

For production workflows that need a publicly trusted PDF certificate, evaluate an appropriate certificate from a recognized provider such as DigiCert, Sectigo, or GlobalSign.

2. Set Up Email

Ensure signing request emails are delivered reliably.

1. Go to WPsigner → Settings → Email
2. Configure SMTP settings (recommended) or use default WordPress mail
3. Customize email templates if desired

Add your company’s branding for a professional experience.

1. Go to WPsigner → Settings → Branding
2. Upload your company logo
3. Set your brand colors
4. Customize the signing page appearance

4. Set Permalinks

WPsigner requires pretty permalinks for signing URLs.

1. Go to Settings → Permalinks
2. Select any option except “Plain”
3. Click Save Changes

Troubleshooting Installation

”Plugin could not be activated”

”Upload failed - file size exceeds limit”

Cause: Server upload limit too small

Solution:

Solution:

1. Increase WordPress memory limit in wp-config.php:

   define('WP_MEMORY_LIMIT', '256M');

2. Deactivate other plugins temporarily to identify conflicts

White screen after activation

Cause: PHP error being suppressed

Solution:

1. Enable WordPress debug mode in wp-config.php:
