    Hello… interesting problem here.

    I just updated my emembers, estore and affiliate plugins and my site is working but the admin area of wordpress just gives me the following error;

    Warning: call_user_func() [function.call-user-func]: First argument is expected to be a valid callback in *********/wp-includes/functions.php on line 2093

    I have tried turning off all plugins in phpadmin and that did nothing so I put them back as they were as to keep my site online.

    My dashboard does not load though and I don’t have any admin access, I also tried creating a new admin user in PHPmyadmin but the same error and trouble is all I get when I log in.

    Any ideas are very welcome at this point,

    thanks, Theo

    Please do the following plugin conflict tests:

    In your case since you cannot access the admin pages you can use FTP to deactivate plugins. Watch the following video (fast forward to 10:01 to see the instructions about how to deactivate using FTP):
