Hi again, caitlincarrol. Do you know what company you host the website with? I asked about COG because this is clearly a subdomain of the COG site, so I figured they have at leastsome association with it.
There are a few reasons why folks can’t log into their dashboards. The most common is they actually don’t know the proper credentials, but that certainly isn’t the only 1. Other reasons include that the site has been compromised and the bad actors deleted the original owner’s account. Google shows me no indication of that, however, but that doesn’t rule the possibility out. Another reason is that you’ve tried too many times and a security plugin (or a firewall at your web hosting company), has blocked your IP address. I’ve rather ruled that out because your webmaster almost assuredly has a different IP than you, and she’s also locked out. A fourth reason is a conflict w/a plugin or theme that’s causing the login page not to work properly.
These are all fixable, but the cause needs to be determined and remedied, and, in order to do so, you’ll need access to your database & file system on the server.
So I guess the question is do you know the credentials for your hosting control panel & do you know how to access the file system there, as well as a program for working w/databases? The latter is often called PHPMyadmin, though there are others.
I am keenly aware this reply is not very helpful, but I’m trying to figure out from another country what tools we have in order to make a way forward. And that w/o benefit of a full quota of coffee, which I am about to go remedy. Please let me know if you can access your hosting control panel in your next reply, what that control panel is, and we’ll try to take it from there. Have a blessed rest of your day.
