Prestashop 1.6.1.24 Admin Panel loads to 404 page

[dannyslade]

Hello,

My 1.6.1.24 install of prestashop loads directly to the 404 page whenever I try to login to the backend. I get the credentials page, but upon logging in, it gets nowhere.

Any suggestions or ideas are appreciated. I've been struggling through this for a few days now.

Thanks,
