6Troubleshooting

Upload Error: “The link you followed has expired”

This typically occurs when your server’s PHP upload limits are too low.

  • Contact your hosting provider to increase PHP upload_max_filesize and post_max_size values.
  • Alternatively, install the plugin via FTP by extracting the ZIP file and uploading the wp-secure-flow folder to your wp-content/plugins directory.

“Destination folder already exists”

This error indicates a previous installation exists:

  • Delete the existing wp-secure-flow folder in wp-content/plugins directory.
  • Proceed with reinstallation as described above.

Site Crashes After Activation

This rare issue typically indicates a PHP version or plugin conflict:

  • Access your site via FTP and rename the wp-secure-flow folder (e.g., to wp-secure-flow-disabled) to deactivate the plugin.
  • Ensure your server is running PHP 7.2 or higher (PHP 8.0+ recommended).
  • Check for conflicts with other security or content protection plugins.

License Won’t Activate

  • Ensure there are no extra spaces before or after the license key.
  • Verify your server allows outbound connections to secureflowsolutions.com.
  • Check that your license is valid and hasn’t reached its site activation limit.
