A client has given me a login so I can admin her website.
She can log in using it, I can't.
She can log in using her login, I can't.
She can log in from home too on both.
I can't log in from my Linux, Windows, or Mac.
She uses an Indian company to do dev, so I don't think it's locked down by IP.
Because I can't get into the system, I don't know much about what's there (including the version, sorry).
What might be wrong?
All ideas appreciated :-)
PS. I'm a developer, but I don't specialise in WP so you'll be well ahead of me.
