Problem

You successfully configured the WebSpellChecker Cloud product (WProofreader, SCAYT) or used the Web API services, but then suddenly the service stops working and you see the CORS error in the console. Below is an example of such an error:


Access to XMLHttpRequest at 'http://staging.webspellchecker.net/spellcheck31/script/ssrv.cgi' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
