..has been blocked by CORS..

we are testing TMS WEB CORE and have the problem that with all web core compos an error occurs: "..has been blocked by CORS..", but in the webserver CORS is enabled. When I test the webservice with a delphi prog, rest-debugger, url in the browser, ... - it runs perfect. What can I do? (i've searched in the support-center for "CORS", but I don't find an answer, sorry)



A CORS problem will show in the browser with the JavaScript call XMLHttpRequest and not in a client application nor when invoking the URL directly from the browser.
If the browser console indicates there is a CORS issue with the XMLHttpRequest access, this means your server is not configured correct.
