Common Troubleshooting Tips

2. Common Troubleshooting Tips

During installation, you may encounter errors. Here’s how to handle them:
  • Error: “Installation Failed Due to Missing File.”
    Ensure the plugin .zip file is correctly formatted and downloaded.
  • Error: “Plugin Already Exists.”
    Check if the plugin is already installed. If so, update it from the Plugins page.
  • Site Becomes Unresponsive After Activation.
    Disable the plugin via FTP by renaming its folder in wp-content/plugins.

Pro Tip:

Always back up your site before installing new plugins. Use tools like UpdraftPlus or BackupBuddy.

3. How to Optimise Plugins for Performance

Installing too many plugins can slow down your website. Here’s how to ensure your site stays fast and efficient:

Choose Lightweight Plugins

Opt for plugins with minimal bloat. Check reviews and ratings for performance feedback.

Pro Tip:

Always back up your site before installing new plugins. Use tools like UpdraftPlus or BackupBuddy.

Update Regularly

Outdated plugins can introduce security vulnerabilities and performance issues.
Go to Dashboard > Updates to check for updates frequently.

Monitor Performance

Use tools like GTmetrix or PageSpeed Insights to evaluate your site’s performance.
  • Example:
    After installing a caching plugin, PageSpeed Insights scores improved from 67 to 85.

4. Best Practices for Managing Plugins

Limit the Number of Plugins

  • Avoid installing plugins for minor tasks.
    Example: Instead of a plugin for simple CSS tweaks, use WordPress’s built-in customiser.

Test for Compatibility

When adding a new plugin, test its compatibility with your theme and existing plugins. Use a staging site for this.

Deactivate and Delete Unused Plugins

Inactive plugins can still slow down your site or pose security risks. Review your plugins regularly and remove unused ones.

  • Install plugins using the WordPress repository or upload method.
