Plugin Upgrade Process

Plugins must be upgraded manually by replacing plugin files on the server.

Manual Plugin Upgrade Steps

  1. Check Current Version
    Go to Admin Panel => Seo Plugins Manager
    Note the current version of the plugin you want to upgrade.

  2. Backup Plugin Data (If Applicable)
    Some plugins store configuration or data:

    # Backup plugin database tables (if any)  
mysqldump -u seopanel_user -p seopanel_db plugin_table_name > plugin_backup.sql

  3. Backup Current Plugin 

    # Backup the current plugin folder  
cp -r /var/www/html/seopanel/plugins/linkdiagnosis \

# Or via FTP: Download the plugin folder to your computer

    https://www.seopanel.org/plugins/

  5. Deactivate Plugin (Optional but Recommended)
    Go to Admin Panel => Seo Plugins Manager
    Deactivate the plugin before replacing files.

  6. Replace Plugin Files
    Via FTP:

    • Delete the old plugin folder (after backing up!)
    • Upload the new plugin folder

    Via SSH: 

    # Remove old plugin (backup already created)  
rm -rf /var/www/html/seopanel/plugins/linkdiagnosis  
# Extract and copy new version  
unzip linkdiagnosis-new.zip  
cp -r linkdiagnosis /var/www/html/seopanel/plugins/  
# Set proper permissions  
chown -R www-data:www-data /var/www/html/seopanel/plugins/linkdiagnosis  
find /var/www/html/seopanel/plugins/linkdiagnosis -type d -exec chmod 755 {} \;  
find /var/www/html/seopanel/plugins/linkdiagnosis -type f -exec chmod 644 {} \;

Plugin Compatibility Check

Before installing or upgrading plugins, verify compatibility:
