    My site http://wizardspost.com/ is WORKING but a strange problem has appeared.
    I was UPGRADING to wordpress latest version when it stalled ( I think) On refreshing it gave the following messages:

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘__return_zero’ was given in /home/wizard/public_html/wordpress/wp-includes/plugin.php on line 166

    Fatal error: Call to undefined function is_multisite() in /home/wizard/public_html/wordpress/wp-login.php on line 85

    Now I cannot login to my wp-admin.
    Can anyone suggest what I should do.
    ——-

    I went to public_html and tried changing Plugins folder in wp-includes. That made it give an additional error and the website too stopped opening.
    So, I restored the original and at least the site started opening again but my problem of not being able to log in for dashboard

    Please could you TRY OUT http://wizardspost.com/wordpress/wp-login to know
