Fatal Error with S2Member. Website down!

To whom it may concern,

Please can you help us immediately. We have had an inundation of s2 member spam registrations (1800+). Those spam registrations then created over 14,000 posts on our website. In order to begin to eliminate these spam registrations from continuing to happen, the very first thing we did right now was update the s2member plugin to the latest version.

Immediately after the plugin was updated we received the following Fatal Error:
Fatal error: Call to undefined function current_user_is() in /home/content/08/9145108/html/wp-content/mu-plugins/s2hacks.php on line 5

Our s2hacks.php only has the following code on it:
<?php
add_action ('plugins_loaded', 'remove_s2_meta_box');
function remove_s2_meta_box()
{
if (!current_user_is('administrator'))
remove_action ('add_meta_boxes', 'c_ws_plugin__s2member_meta_boxes::add_meta_boxes');
}

Now the entire website will not work. If you go to http://www.thewaronevil.com the only thing you see is the fatal error message. There is now no ability to access the WordPress admin dashboard. As if things weren't bad enough with the inundation of spam registrations now this had to happen.

How do we fix this? We don't even know where to begin. Thank you for any and all of your assistance.

Sincerely,

Ed.

Hello Ed,

It’s strange you get that error. I believe current_user_is() is actually a WordPress function…

I believe you should be able to access the admin side. Going to http://www.thewaronevil.com/wp-admin/ …

I just had a similar error and got it fixed by going to my hosts Cpanel.

I went in to my hosts server side Cpanel and in the file manager tried renaming the file and was able to login
but then received these errors

In my case I was able to identify the plugins giving the errors… azon profit poster and another plugin called associate Goliath… two plugins having issue because of updates to clickbank and amazon..deactivated , notified the developer and now back to normal.
How this helps but it appears that your using multi site; (http://premium.wpmudev.org/manuals/wpmu-manual-2/using-mu-plugins/) and I dont know anything about the theme or its plugins but Im posting anyway to give you an idea of where to start ….

Perhaps you could do the same .. go in from the cpanel manager side from your host and remove the plugin restore the site and go from there…

Thanks for the heads up on this thread :-)

The current_user_is() function, is an API Function provided by s2Member®. So if s2Member® is disabled (which it IS momentarily during an update of the plugin); you will see this error. The solution is to disable your s2-hacks.php file during the update. Or, to use a function_exists check before you use this function.

Ex: if(function_exists('current_user_is') && current_user_is())
