The Problem
W3 Total Cache minifies and combines JavaScript files on your site to improve page load speed. However, cookie consent banners need to load early - before other scripts run - to properly block tracking cookies and comply with privacy regulations like GDPR and CCPA.
When W3 Total Cache minifies or combines the Kukie.io banner script, the banner may not appear at all, or it may malfunction.
Symptoms
If W3 Total Cache is interfering with your cookie banner, you may notice:
- The cookie banner does not appear on your site
- The banner appears but consent choices do not work
- JavaScript errors in the browser console related to the banner script
- Cookies are set before the visitor has given consent
How to Fix
You need to exclude the Kukie.io banner script from W3 Total Cache's JavaScript minification. Go to Performance > Minify in your WordPress admin.
Step 1: Exclude from JS Minify
If JS minify is enabled, scroll down to the Never minify the following JS files field and add:
cdn.kukie.ioStep 2: Check Embed Settings
In the same Minify section, ensure the Kukie script is not being combined with other scripts. If JS embed type is set to combine files, the exclusion from Step 1 should be sufficient - W3 Total Cache will skip excluded files during combination.
Step 3: Clear Cache
After saving, go to Performance > Dashboard and click Empty All Caches. Then check your site in an incognito/private browser window to verify the banner appears correctly.
Tip: If you are using the Kukie WordPress plugin (version 1.2.0+), the banner script tag includes
data-no-minify,data-no-defer, anddata-no-delayattributes. W3 Total Cache may recognise these and skip the script automatically. If the banner still does not load, add the manual exclusion as described above.
