But before proceeding, it's essential to confirm whether Mod_Pagespeed is already integrated with your website. You can do this by visiting ismodpagespeedworking.com or using the following command:
curl -D- https://cutecatz.lol/ | less
Replace "cutecatz.lol" with your actual domain name.
Method 1: Turning On/Off
- Turning Off Temporarily: If you encounter issues with your website after enabling Mod_Pagespeed, you can temporarily deactivate it by adding the following line to your
.htaccessfile:
ModPagespeed standby
Replace "standby" with "off" for a complete shutdown.
-
Turning Back On: To re-enable Mod_Pagespeed, simply replace "standby" or "off" with "on" in your
.htaccessfile. -
Complete Deactivation (Advanced Users): For VPS or dedicated server users with root access, you can use the following command to completely turn off Mod_Pagespeed on a system-wide level:
ModPagespeed unplugged
Important Note: This method overrides any attempts to enable Mod_Pagespeed for specific virtual hosts.
Method 2: Configuration (Advanced Users)**
While enabling Mod_Pagespeed provides a good starting point, you can further customize its behavior by adding specific filters to your .htaccess file. Caution: Improper configuration can negatively impact your website. It's recommended to consult a developer for advanced configuration.
Verifying Results
Once you've enabled or configured Mod_Pagespeed, test your website's performance using:
- Google PageSpeed Insights: https://developers.google.com/speed/docs/insights/v5/about

Remember, a perfect score isn't everything. Focus on achieving a noticeable improvement in loading speed while maintaining website functionality.
WordPress and Mod_Pagespeed
While WordPress is the most popular Content Management System (CMS) on the planet, it's not necessarily known for its blazing-fast speed. Many WordPress users rely on plugins to minify JS and CSS files for optimization. Here's what to consider when using both Mod_Pagespeed and WordPress plugins:
-
Plugin Conflicts: Be cautious with WordPress optimization plugins when using Mod_Pagespeed, as they can conflict and cause website issues, especially with contact forms. It's recommended to disable these plugins first and gradually re-introduce them if necessary.
-
Minimize Plugins: Generally, avoid using excessive plugins on your WordPress site. Delete or disable unused plugins, and consider custom coding for minor tweaks instead of bulky plugins that load additional resources.
-
Testing is Key: Thorough testing is crucial before fully enabling Mod_Pagespeed on your WordPress website. Conflicts might not be immediately apparent, so test, test, and test again!
Image Optimization with Mod_Pagespeed
Pagespeed can optimize common image formats (GIF, PNG, JPEG) and convert them to WebP for better compression. While WebP
Remember, a perfect score isn't everything. Focus on achieving a noticeable improvement in loading speed while maintaining website functionality.
Troubleshooting: Potential Gotchas and Solutions
1. ModPagespeed Rewrites URLs and Potential Conflicts:
- ModPagespeed might rewrite HTML references to resources (e.g., stylesheets) with modified names for caching purposes. This can cause issues if the browser requests the resource from a different server that doesn't have ModPagespeed installed.
- Solution: You can configure ModPagespeed to map the origin domain of rewritten resources using directives in your Apache configuration file (
.htaccess). This ensures resources are fetched from the correct location. Refer to the ModPagespeed documentation (https://www.modpagespeed.com/doc/) for detailed instructions.
2. Cloudflare and ModPagespeed:
- While generally compatible, using both Cloudflare and ModPagespeed for website optimization can lead to redundancy, potentially causing conflicts. The same may apply when using CloudLinux WordPress AccelerateWP.
- Solution: Consider disabling compression in Cloudflare if you're using ModPagespeed for compression. Additionally, if you have CSS/JS minification enabled in both Cloudflare and ModPagespeed, disable it in one to avoid conflicts.
- Additional Note: Cloudflare offers its own CDN and optimization services. Depending on your website's needs, using ModPagespeed might be redundant. Evaluate which solution provides the best performance for your specific scenario.
3. WordPress and ModPagespeed:
- WordPress plugins that minify CSS/JS files might conflict with ModPagespeed's optimization, potentially breaking your website.
- Solution: It's recommended to disable these plugins temporarily while using ModPagespeed. If necessary, re-enable them one by one and test them thoroughly to identify any conflicts.
- General Best Practice: Avoid using excessive plugins on your WordPress site. Delete or disable unused plugins and consider custom coding for minor tweaks instead of relying on plugin functionality. This can improve overall website performance.
- Testing is Crucial: Always test thoroughly after enabling ModPagespeed on your WordPress website. There might be a delay before conflicts become apparent.
4. ModPagespeed Broke My Site! What to Do?
- If you encounter issues after enabling ModPagespeed, don't panic. Here are steps to help diagnose and resolve the problem:
- Disable Compression in WordPress Plugins: If you're using compression plugins, disable them temporarily to allow ModPagespeed to handle compression.
- Temporarily Disable ModPagespeed: Append
?ModPagespeed=offto your website's URL. If the site functions normally, the issue is likely related to ModPagespeed's rewriting or HTML parsing. - Identify Conflicting Filters (Advanced Users): If disabling ModPagespeed resolves the issue, try enabling it again with specific filters turned off one by one. Append
?ModPagespeed=on&ModPagespeedFilters=followed by the filter name (e.g.,combine_css) to the URL and test. This can help pinpoint the problematic filter. Refer to the ModPagespeed documentation for a list of available filters.
Remember:
- Always back up your website before making any configuration changes.
- Start with a conservative approach and test thoroughly before deploying changes to your live website.
- Consult the ModPagespeed documentation for a comprehensive list of filters and their functionalities.
