If your Cookie Box is not displayed or displayed incorrectly, the problem can often be attributed to one of these four causes.
Caching system active
If used, disable your caching system (like Autooptimize, WP Rocket, …). Now test again wether the Cookie Box is displayed. Please use the incognito mode of your browser.
Caching systems interact with features of Borlabs Cookie and should always be disabled for testing. If everything works as expected, you can reactivate your caching system.
"Do not track" enabled
If the Cookie Box is not displayed, check whether a "Do not Track" function is active in your browser settings or via plugin. If so, you have to deactivate this option.
Adblocker or uBlock active
A white bar instead of the Cookie Box is in almost all known cases an indication that an AdBlocker with activated cookie hint suppression or another plugin like uBlock is active. Here the blockers simply look for words like "cookie" in the names of the CSS classes or attributes of HTML elements and block them. We can't do anything about it, visitors have to turn off their AdBlocker or at least disable the setting for cookie hint suppression.
wp_footer()-Funktion fehlt
Please make sure that your theme calls the WordPress function wp_footer(); in the footer.php just before the </body>-tag. This function call is often forgotten in custom themes. Borlabs Cookie uses this hook to load its Cookie Box and JavaScript files.
