Error AADSTS501481: The Code_Verifier does not match the code_challenge supplied in the authorization request.

Hello,

Thank you very much for this code/app.

I regularly get the error AADSTS501481: The Code_Verifier does not match the code_challenge supplied in the authorization request. When this happens, I can use a private window, but that's not a solution for my visitors. I've searched a bit on the Internet, but in fact I don't master php enough to solve this problem.

My site has a home page (index.php) and application directories with files that all refer to a template that contains the authentication code. The return file (oauth) is located at the root with the index.php file.

Could someone help me?

Thanks by advance.
