Fixing Common CSS and JavaScript Conflicts with The Events Calendar

If your website's styling or functionality breaks after installing The Events Calendar, you're not alone. A frequent cause is a conflict between the plugin's scripts and your theme or other plugins. This guide will help you understand why these conflicts happen and how to resolve them.

Why Do These Conflicts Occur?

The Events Calendar loads its own CSS and JavaScript files to power its event views and features. In some cases, these files can:

  • Override styles from your theme (e.g., font weights, margins, header colors).
  • Replace core WordPress libraries, which can break functionality in other plugins or theme editors (like the Divi Builder).
  • Interfere with aggressive caching or optimization plugins that combine or delay scripts.

Common Solutions to Try

1. Test for a Conflict

The first step is always to identify the source of the problem. Temporarily deactivate all other plugins and switch to a default WordPress theme like Twenty Twenty-Four. If the issue disappears, reactivate your plugins and theme one by one to find the culprit. This is the most reliable way to diagnose a conflict.

2. Exclude Plugin Assets from Caching

Performance plugins (e.g., SiteGround Optimizer, WP Super Cache) can break The Events Calendar by optimizing its files. To prevent this, you often need to exclude the plugin's CSS and JavaScript from being cached. The common file paths to exclude are:

/wp-content/plugins/the-events-calendar/(.*).css
/wp-content/plugins/the-events-calendar/(.*).js
/wp-content/plugins/event-tickets/(.*).css
/wp-content/plugins/event-tickets/(.*).js

Consult your caching plugin's documentation for instructions on how to add these exclusions.

3. Use More Specific CSS

If the plugin is overriding your theme's styles (a common issue with Divi and Astra themes), you may need to override the plugin's CSS with more specific rules. Use your browser's inspector tool to identify the classes being applied and then add your own CSS with a higher specificity, often using the !important declaration as a last resort.

/* Example: Fixing a dropdown menu being cut off */
.tribe-events .tribe-events-header {
    overflow: inherit !important;
}

Add this kind of custom CSS in your theme's Customizer under Additional CSS.

4. Check for Known Theme-Specific Issues

Some themes, like Divi, have known compatibility notes. The 'The Events Calendar' team provides a knowledgebase article for using the plugin with Divi. It's worth checking if such a resource exists for your specific theme.

When to Seek Further Help

If the steps above don't resolve your issue, the problem might be more complex. When seeking help in community forums, be prepared to provide:

  • The URL of your calendar page.
  • A list of your active plugins and theme.
  • Any specific error messages from your browser's console (F12 Developer Tools).

By systematically testing and applying these common fixes, you can usually restore your site's appearance and functionality while still enjoying the powerful features of The Events Calendar.
