    Dear WordPress enthusiasts,

    I've problem activating Events Manager Version 5.2.6 in WordPress Version 3.4.2

    The plugin downloads and installs successfully.
    While the plugin is activated the WordPress Dashboard is not accessible.
    This may have caused because of error of somekind.
    from the error_log I've found the following error

    [21-Oct-2012 12:00:42 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'add_warp' not found or invalid function name in /home/site/public_html/renewchurch/wp-includes/plugin.php on line 403

    From my past experience I've noticed that the use this function with valid callback will solve the problem.

    call_user_func_array() is used on the following file
    events-manager/classes/phpmailer/class.phpmailer.php
    line number 2521

    protected function doCallback($isSent, $to, $cc, $bcc, $subject, $body) {
    if (!empty($this->action_function) && function_exists($this->action_function)) {
    $params = array($isSent, $to, $cc, $bcc, $subject, $body);
    call_user_func_array($this->action_function, $params);
    }
    }

    I'm not sure what to do with this but hope I'll find a solution.

    Kind Regards

    Are you sure the plugin is compatible with 3.4.2?

    I'm not sure if the plugin is compatible or not with 3.4.2 because I couldn't not activate it on 3.4.2

    Have you tried to temporarily:

    - deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
    - switching to the default theme to rule out any theme-specific problems

    yes, it works fine with 3.4.2

    are you sure you don't have another php error in your log? the above wouldn't stop your dashboard from working, you should see a fatal error there somewhere.

    also, i'm pretty sure it can't be that line because before that call in the if function there function_exists($this->action_function) meaning call_user_func_array wouldn't be called if the function didn't exist.

    I have the same issue. Admin panel goes blank as soon as I activate Events Manager.

    you'd need to check your php logs, or try angelonwl's suggestion to figure out the problem. EM works fine under normal circumstances.

    It was a PHP Memory Limit issue. I upped the limit in my PHP configuration from 32M to 128M and that solved the problem.
