Sometimes, errors such as 400, 401 or 500 occur in Haiilo when there is something not currently working correctly. Often these errors are caused by browser cache having an effect on Haiilo and the easiest way to remedy this is to clear the cache in your browser. 

Most often if you contact Haiilo about receiving an error message, we will ask you to empty cache first to ensure that it is not the root cause of your issue before investigating further.  

You can clear cache in your browser in different ways depending on the browser and operating system that you are using. This guide will explain how to clear cache for the most common browsers.
