Cannot login as Site Admin

I cannot login as Site Admin in my club's FTH page. The ID and password seem to be accepted, but the sign on process just hangs after that and never returns any error, therefore I have no idea what's wrong. I am using the correct admin password and others in my club are not experiencing this issue. In addition, I have been able to login as site admin in the past. I am the current club VPPR and need to make some changes on the website.

I think this is because your admin email address is a club address used by FreeToastHost for forwarding emails. The admin address cannot be a FreeToastHost address. I suspect the same applies to custom domains.

Please follow the steps to request admin access when the original admin is no longer available: support.toastmastersclubs.org/doc/item/w...-no-longer-available
Use your private email address for administrator access.

1) your Admin email was invalid

2) there was a bunch of base64 at the bottom of your home page I have removed.

Thank you for your response.
I do have some further questions.
1. Other club members are not having the same issue I'm experiencing - they are able to sign in as site admin. Why am I affected and they aren't?
2. You mentioned that our Admin Email is invalid - I think our previous VPPR may have set that address to vppr-1059533@toastmastersclubs.org. I think that address is forwarding to me at mto51796@yahoo.com. Could that be why I'm affected and others are not?
3. Since others in the club can sign on as Site Admin, can I ask one of them to change the Admin Email?

already changed.

You cannot use @toastmastersclubs.org emails or any email address w/ your custom domain in any of the form fields asking for an email address--it causes email and system hangs. (basically causes the system to run in circles) We specifically try to prevent that from happening, but it appears this may have somehow slipped through our defenses.
