CORS policy: No Access-Control-Allow-Origin

Hello to the community!
I plan to enable users on my aggregator to add a chat widget individually, that is, each participant of the platform independently registers on, creates a widget and inserts the code in the personal account of our platform, so each participant should have his own individual chat on his business page and real estate objects.

We have successfully implemented these features, but there is a problem that the buttons on the widget are not displayed on user pages. after studying, such an error was discovered:

Access to script at ‘’ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Has anyone encountered this, can help with the solution?!


this might help Help Center | | How to resolve Content Security Policy (CSP) issues blocking widgets and images

but I guess you have to enable ‘Access-Control-Allow-Origin’ on your server I think is not directly related to the plugin

Hi! Useful information, but unfortunately I can’t manage the server and make similar settings in shared hosting (

maybe you could ask your hosting service to Add the Domain into the Whitelist for Content Security Policy.

good luck let us know if you could fix it.
