EspoCRM not working for CORS reason

I’ve just installed EspoCRM from Softaculous Installer.

I can’t save any entity on system because of this error.

Failed to load https://infinityfree.net/errors/403/: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://[mysite].epizy.com’ is therefore not allowed access.

This is because of the Security System.

The error described indicated by @UnknownLolz does prevent CORS, but that shouldn’t be a problem if you’re trying to do something on a single domain. Did you try to move your script installation to another URL? If so, you need to make sure that all settings and configurations use the new URL.
