Hello,

I’m a new user of Hubspot CRM and I tried to install a chat in my website [https://www.warenghem.com](https://www.warenghem.com) (powered by Wordpress).

But I have an error in my console:

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘[https://app.hubspot.com](https://app.hubspot.com)’) does not match the recipient window’s origin (‘[https://www.warenghem.com](https://www.warenghem.com)’).

It seems that there are no similar issues on the web, could you help me, please?

Thank you a lot and have a great day !

Kevin

Hi @kevinbrosseau

The chat window is loading for me when I visit your site in Chrome, Firefox and Edge browsers and I don’t see that error message in the console (though I see a few Wordpress script errors in there). Is this still happening for you? If so which browser are you using?  
These kinds of errors can sometimes occur if a page is slow to load or can be temporary.

Thank you for your answer,

Is was Aguard and Privacy badger extension. It’s working know as they are disabled.

But it is not a good thing because Intercom chat (for example, I saw it) is showing well with these extensions enabled.

Thank you !

Kevin

Just one more question, it is not possible to insert custom CSS ?
