Resolving Divi’S Javascript Issues With Autoptimize

Posted on

JavaScript (JS) issues can be frustrating, especially when they impact crucial page elements on your website. If you're encountering JavaScript problems specifically on the front end of your site while using Divi and Autoptimize, you're not alone. This guide aims to help you diagnose and resolve these issues effectively.

Understanding the Problem

You've noticed that JavaScript is disabled only on the front end of your website, causing JS-dependent page elements to malfunction or disappear entirely. However, JavaScript continues to work correctly on the back end when you're logged in to WordPress/Divi. This discrepancy suggests that the issue lies in how JavaScript is optimized or processed for the front end.

Isolating the Culprit

You've already taken some proactive steps to isolate the problem, including:

  1. Disabling all other plugins to rule out conflicts.
  2. Identifying that the issue is directly related to Autoptimize's "Optimize JavaScript Code" setting.

Autoptimize and JavaScript Optimization

Autoptimize is a popular WordPress plugin that optimizes various aspects of your site, including CSS, JavaScript, and HTML. While it can significantly improve site performance by minifying and caching these resources, it sometimes causes compatibility issues with certain themes or plugins, such as Divi.

Divi's Inline JavaScript and CSS

Divi, a versatile WordPress theme builder, often utilizes inline JavaScript and CSS to control various design and functionality aspects. These inline scripts and styles may interact with each other dynamically to create the desired visual effects and behaviors.

Proposed Solution

To address the JavaScript issues while still benefiting from Autoptimize's optimization features, you can try the following steps:

  1. Excluding Divi's Inline Scripts and Styles:

    Since Divi's inline JavaScript interacts with inline CSS, it's crucial to ensure that both are excluded from Autoptimize's optimization process. You can achieve this by adding specific exclusions for Divi's inline scripts and styles.


    Adding these identifiers to Autoptimize's exclusion settings should prevent the optimization of Divi's inline JavaScript and CSS, potentially resolving the JavaScript issues on the front end.

  2. Testing and Monitoring:

    After implementing the exclusions, thoroughly test your website's front end to ensure that JavaScript-dependent elements function correctly. Monitor your site's performance and behavior over time to verify that the issue has been successfully resolved.

  3. Alternative Optimization Strategies:

    If excluding Divi's inline scripts and styles doesn't fully resolve the JavaScript issues or negatively impacts site performance, consider alternative optimization strategies. You may experiment with different settings in Autoptimize or explore alternative optimization plugins compatible with Divi.

  4. Update Divi and Autoptimize:

    Ensure that you're using the latest versions of both Divi and Autoptimize. Developers often release updates to address compatibility issues and improve overall performance. Updating these components may also help mitigate the JavaScript problems you're experiencing.

Further Troubleshooting Steps

If the proposed solution doesn't completely resolve the JavaScript issues, consider the following additional steps:

  • Review Console Errors: Inspect your browser's developer console for any JavaScript errors or warnings. These messages can provide valuable insights into the root cause of the problem.

  • Check Theme and Plugin Compatibility: Verify that your theme (Divi) and any other plugins you're using are fully compatible with the latest versions of WordPress, Divi, and Autoptimize. Incompatibilities or outdated components can lead to unexpected behavior.

  • Consult Community Forums: Reach out to the Divi and Autoptimize communities for assistance. Forums, discussion groups, and social media platforms are excellent resources for troubleshooting specific issues and receiving expert advice.

  • Consider Professional Support: If you're unable to resolve the JavaScript issues on your own, consider seeking assistance from WordPress developers or specialists familiar with Divi and Autoptimize. They can offer personalized guidance and solutions tailored to your website's unique configuration.


Dealing with JavaScript issues, especially in conjunction with optimization plugins like Autoptimize, can be challenging. By understanding the interaction between Divi's inline scripts, Autoptimize's optimization processes, and your site's front-end functionality, you can effectively troubleshoot and resolve these issues.

Remember to implement the proposed solution, test thoroughly, and monitor your site's performance closely. Don't hesitate to explore alternative strategies or seek assistance if needed. With patience and persistence, you can ensure that your website delivers a seamless user experience with fully functional JavaScript elements on the front end.
