Resolving Common Hostinger Tools Plugin Update Errors

Users of the Hostinger Tools plugin for WordPress occasionally encounter errors after updating to a new version. These issues can range from PHP fatal errors to problems with the WordPress editor. This guide covers the most common update-related errors and provides steps to resolve them.

Common Update Errors and Their Solutions

1. Fatal PHP Errors (e.g., "Class Not Found")

The Problem: After an update, a fatal PHP error appears, often mentioning an undefined class or a specific line number in a plugin file (e.g., hostinger.php on line 83). This can make a site or its admin dashboard inaccessible.

Why It Happens: This is typically caused by incomplete file updates or a corrupted installation during the automatic update process.

The Solution:

  1. Manual Reinstallation: The most effective fix is to manually reinstall the plugin. To do this:
    1. Access your site's files via FTP or your hosting file manager.
    2. Navigate to the /wp-content/plugins/ directory.
    3. Delete the entire hostinger or hostinger-tools folder. Note: This will not affect your site's core data.
    4. Go to your WordPress admin dashboard > Plugins > Add New.
    5. Search for "Hostinger Tools," install it, and activate it again.
  2. Check for a Newer Update: The Hostinger Tools team is often quick to release patches. After a manual reinstall, check if a newer version is available that may have fixed the specific error.

2. WordPress Editor or Customizer Breaks

The Problem: After an update, you may encounter JavaScript errors when trying to edit posts or pages, or see an error like "Looks like something's gone wrong" when saving theme customizations.

Why It Happens: A new version of the plugin may have a bug that introduces a JavaScript conflict with your theme or other plugins.

The Solution:

  1. Update Immediately: These types of bugs are usually fixed very quickly. Check for another plugin update, as a patch has often been released within days (e.g., version 2.1.5 fixed an issue introduced in 2.1.4).
  2. Clear Cache: After updating, clear your browser cache and any server-side or plugin-based caching (like LiteSpeed Cache) to ensure the new, fixed JavaScript files are loaded.

3. PHP Warnings and Notices

The Problem: Non-critical warnings about undefined variables may appear in your admin area or on the front end, often related to companion plugins like "Hostinger Easy Onboarding."

Why It Happens: These are typically code warnings that don't cause fatal errors but indicate areas where the code should be improved for compatibility.

The Solution: Ensure all your Hostinger-related plugins are updated to their latest versions, as these warnings are commonly addressed in subsequent releases.

General Best Practices for Plugin Updates

  • Always Have a Backup: Before updating any plugin, ensure you have a recent full backup of your WordPress site and database.
  • Check the Changelog: The Hostinger Tools plugin changelog contains information on what's new and what has been fixed. Note that it may list versions in chronological order, so check the bottom of the list for the most recent updates.
  • Update in a Staging Environment First: If possible, test major updates on a staging copy of your site to identify potential conflicts before updating the live site.

Following these steps should resolve the majority of issues that arise after updating the Hostinger Tools plugin. If a problem persists after trying these solutions, it may be helpful to seek advice from the wider WordPress community forums, detailing your specific error message and WordPress environment.
