I accidentally downloaded my Twenty Eleven theme files and I attempted to abort it but it kept downloading. I saw several messages about error in file while it was downloading. Afterwards, I couldn't access my WordPress Dashboard through wp-admin and when I try to the browser screen is blank under the address of http://roundhousetalk.com/wp-admin/nav-menus.php. I deleted the Twenty Eleven theme and downloaded and then uploaded a fresh Twenty Eleven theme folder. Same result. When I go to my URL for my site it the content comes up without any error but still unable to access the Admin Dashboard. Is there anything I can do?
