405 Error when attempting to update Library location

Hi all,

I’m running into an issue when trying to update the library location in Xibo 2.1.0. The cmslibrary folder is on the D drive within xibo-cms-2.1.0. When I log into Xibo and go to settings to update the library location I get a server error image, “405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access.”

Environment:
Windows Server 2016
MYSQL 8.0
PHP Manager 2
No docker
IIS 10
PHP 7.2
Xibo Player 2.0.200 (if that matters)

Originally installed Xibo 2.0.3 and it was running fine until we decided to upgrade to 2.1.0. there were a few issues within 2.0.3 (wasn’t explained to me) so I handled the upgrade with the existing database (initially new DB, but we dropped it). Either way the issue is present when attempting to change and save any settings. Appreciate any help and let me know if you need more info from me.

Thanks!

Edit: I also get this issue when trying to change my password.
