ADMIN LOGIN ISSUE

Sure. You just go to http://yoursite.com/wp-admin. That will take you to the login page, and to the admin area.

First up, that link is wrong. There’s no .php extension on that. It would be just http://www.charitycrowdfund.co.uk/wp-admin/

Second, what plugins are you running on that site, because when I go to what should be the right URL, it redirects to http://www.charitycrowdfund.co.uk/login-2/ and that’s definately not something that’s part of the standard WordPress system.

Assuming that it’s the theme or a plugin that’s the problem, you’ll need to reset the plugins, and maybe the theme, manually. That should let yo uget back into the admin area, and from there you can start finding out which plugin has actually broken your site.
