I moved my wordpress blog from a sub-domain to my main domain. My website is working fine, but now I can't access my wordpress dashboard. I get this error:
Fatal error: Cannot redeclare get_temp_dir() (previously declared in /home/grandst8/public_html/wp-includes/functions.php:2160) in /home/grandst8/public_html/wp-admin/includes/file.php on line 189
Any ideas how to fix this?
