No Access to wp-admin

I am trying to login to my ww.wp.xz.cn site using wp-admin but I only get the following page:

Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /homepages/19/d104722270/htdocs/clickandbuilds/WordPress/roadtripusa/wp-content/plugins/contentclick/includes/functions.php on line 25

There’s no login option.

I did try to use wp-login which displayed a login box but would not accept my login detais. I attempted to reset my password but clicking the link in the email only displays the above warnings, so I’m unable to sucessfully do that. I’ve now managed to lock out my account and recieve the follwoing message: Your IP (nn.nn.nnn.nnn) has been flagged for potential security violations.

Any advice would be greatly appreciated.
