Why am I getting an "invalid chatbox code" or "Invalid Website" error ?

*This error code is in general due to a configuration issue on your end*

1. Lock chatbox to domain option

For security concerns, we added an option "Lock the chatbox to website domain (and sub-domains)". By enabling this option, Crisp disallow other website domains to use your Crisp.

If your Crisp website domain is www.mydomain.com , then your chatbox is locked for mydomain.com
If you are using *localhost* , your chatbox is locked to mydomain.com

In general, you have to strictly use this lock option, only if you understand this security concern.

*Otherwise, just disable it:*

Navigate to Settings > Workspace Settings > Chatbox Security
Disable "Lock the chatbox to website domain (and sub-domains)"

Disable the lock chatbox to website domain option

2. Wrong chatbox code

Maybe you did a wrong copy-paste. In general, your chatbox code should look like this:

<script type="text/javascript">window.$crisp=[];window.CRISP_WEBSITE_ID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";(function(){d=document;s=d.createElement("script");s.src="https://client.crisp.chat/l.js";s.async=1;d.getElementsByTagName("head")[0].appendChild(s);})();</script>

Your WEBSITE_ID would look XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX with only alphanumeric characters.

3. You deleted your website

You may have deleted your website from the Crisp dashboard. In this case, go to https://app.crisp.chat/settings/websites/ and check if your website is missing.

*If using Wordpress*, please relink your website, by going to your Wordpress Admin Panel, and then Crisp Livechat admin settings. *Relink your Crisp* then.
