Your website doesn’t seem to be hosted by WordPress.com, instead it is using the WordPress.org software on your own server (self-hosted). This forum is for providing support only for websites hosted on WordPress.com
There are two versions of WordPress – WordPress.com and WordPress.org. You can find more information about the differences between them here.
I would suggest that you look at the support page of WordPress.org and their forum – https://wordpress.org/support/. If you don’t have an account there you can create one for free here.
