Can't login to wordpress site all of a sudden

I updated to the lastest wordpress file

“file”?

you mean latest version?…

Yes version

Perhaps your theme was not compatible with the latest version of WordPress or there is a misconfiguration.

Looks like your login form is here –
https://s332030627.onlinehome.us/usf/wp-login.php

Ya I can’t login unfortunately. It gives me a 500 error

Why is your login at this domain – https://s332030627.onlinehome.us/usf/ when your wp site is at this domain – https://www.sendabull.com ?

I have a host with a bunch of websites on it. Sendabull.com points road folder called USF on that host. D

Contact your host.

Why?

I have a similar problem.

I did an upgrade and can’t get in at all. It want’s me to create another wordpress account. Any suggestions would be great.

I have been in touch with the host (webcity). All is fine with them…and the files appear to still be there, just wordpress not playing?

Thanks – Belle

Jason,

How can I fix this for future reference? I have another site https://www.engage24.org that does the same thing and it keeps looking back to the other address.
