Resolving Common PHP Warnings and Errors in the SeedProd Coming Soon Plugin

33 threads Sep 16, 2025

If you're using the Website Builder by SeedProd and have encountered PHP warnings or errors, you're not alone. These messages are a common occurrence, especially after updating your PHP version or the plugin itself. While often non-critical, they can be confusing and clutter your debug logs.

This guide will walk you through the most frequent PHP-related issues reported by users and the recommended steps to resolve them.

Common PHP Warnings and Their Fixes

1. Double Underscore Method Name Warnings

Problem: A warning stating: Method name "SEED_CSP4_ADMIN::__return_empty_string" is discouraged; PHP has reserved all method names with a double underscore prefix for future use.

Why it happens: This is a warning from PHP 7 and above, which reserves method names starting with a double underscore. It does not prevent the plugin from functioning.

Solution: The SeedProd team has acknowledged this warning in the past and typically addresses it in a subsequent plugin update. You can safely ignore it until an update is available.

2. Undefined Variable or Property Warnings

Problem: Warnings like Undefined variable $get_request_uri or Undefined property: stdClass::$redirect_url appearing in your logs or on your site.

Why it happens: These occur when the code attempts to use a variable or access an object property that hasn't been defined or set. This is common when moving between PHP versions, such as from 7.4 to 8.0, which has stricter error reporting.

Solution: For the redirect_url warning, a specific workaround has been suggested:

  1. Navigate to Landing Pages -> Coming Soon Mode -> Edit Page Button -> Page Settings.
  2. Enable Redirect Mode and add a sample URL.
  3. Click Save.
  4. Disable Redirect Mode and save the page again.

This process can often initialize the missing setting and clear the warning.

3. Use of Undefined Constant 'php'

Problem: A warning: Use of undefined constant php – assumed 'php' in a file like seedprod-preview.php.

Why it happens: This is typically caused by the use of short open tags (<?) when they are not enabled in your PHP configuration.

Solution: The SeedProd team has identified this as an issue related to short tags being enabled and has released updates to correct it. Ensure your plugin is updated to the latest version.

4. File Permission Errors During Update

Problem: An error stating that files cannot be copied during a plugin update, often due to file permission inconsistencies.

Why it happens: This is a server-level issue, not specific to the SeedProd plugin. It occurs when the WordPress user does not have the correct write permissions for the plugin directory.

Solution: You will need to contact your web hosting provider's support team. They can adjust the file permissions on your server's wp-content/plugins/ directory to allow WordPress to update plugins correctly.

General Troubleshooting Steps

  • Update the Plugin: Always ensure you are running the latest version of the SeedProd plugin, as many warnings are patched in subsequent releases.
  • Check PHP Version Compatibility: The plugin is generally compatible with PHP 7.3, 7.4, and 8.0. However, stricter error reporting in newer versions (like PHP 8.0) may reveal warnings that were previously hidden.
  • Temporarily Disable Error Display: While waiting for a fix, you can prevent warnings from displaying on your live site by turning off debug mode in your wp-config.php file. Set WP_DEBUG to false. Your web hosting provider can assist with this.

Most PHP warnings related to the SeedProd plugin are minor and do not affect functionality. The development team is generally responsive to fixing these issues once they are reported. For persistent problems not resolved by an update, checking the official WordPress support forums for the plugin may provide additional user-shared solutions.
