While I developed an application with Flutter web and php APIs, I did not have any problems with CORs when it was running locally, but whenever I wanted to put the application into production, CORs errors were flooding. I researched the reason but could not find a solution, all solutions only make it work locally.
Please help, thank you.
I gave all permissions for all the APIs I wrote with PHP;
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: *");
header("Content-Type: application/json");
However, the problem still persists and CORs errors are flooding in production.
