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.
