Hi,

I have this error in my JavaScript console, where can it come from?

DevTools failed to load SourceMap: Could not load content for http://127.0.0.1:8091/scriptcase/prod/third/tiny_mce_new/js/tinymce/skins/lightgray/skin.min.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Thanks
