  • Steps to reproduce the issue:

Hello support,
When I upload the project to IIS, I get a CORS error in Update and Delete operations, but I do not get an error in the Insert process. However, http: // localhost: 4200 is written in the settings file of the project.

Access to XMLHttpRequest at 'http://localhost:7878/api/lepton-theme-management/settings' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
