example.com/wp-admin not logging in

Hello, db1500, & welcome to the WordPress support forum. Actually, it’d be really helpful if you provided a real site url as opposed to example.com. That way, we can have a look & see if there’s anything that might help us diagnose your problem. You also don’t say whether this is a single or a multisite installation. which would also be very helpful to know.

There are a lot of things that can cause this, including a plugin/theme conflict, a plugin that does its own logins, a misconfigured multisite installation, & that’s just getting started. Somehow I suspect a plugin that takes the place of the login dashboard (1 I know that does this is Ultimate Member, but there are others). We could much more easily help you troubleshoot this if you provide a site url, as well as a list of plugins you’re running.
