Hi @paul2009,
thank you very much for your reply.
I contacted Squarespace Costumer Service, and got this not useful message below.
Do you think there is a way to solve the 'Acess-control-allow-origin' header issue with Cors policy? Or is it a problem with Squarespace Servers?
Thank you!
Hi Cleber, Thanks for getting back to us. I understand that you haven't received the reply you were hoping for. While you're welcome to use CSS, we aren't able to offer troubleshooting support for advanced modifications like custom code. I searched our support guides for common errors, and did see a section in our guide which notes: "You'll receive a CORS error if you use JavaScript to make requests from a browser. All requests must originate from a server side application. We don't support CORS requests." I'm not sure if that is helpful information, but since you mentioned CORS policy, I thought it worth mentioning. You can view that section of the guide here: https://support.squarespace.com/hc/en-us/articles/205815928#toc-if-you-receive-a-cors-error Although we are unable to offer support for CSS, there are a few popular and credible websites we recommend for tutorials, troubleshooting, and reference guides:
W3Schools
Codecademy
Mozilla Developer Network
Stack Overflow
Shay Howe
SitePoint
Treehouse
I hope some of this information is useful. If you have any additional questions, please let us know and we will do our best to help.
