I am having problem with the login widget included

Hello.

I am having problem with the login widget included in the membership plugin.

The widget doesn't appear instead a error message

"Fatal error: Call to undefined function do_shortcde() in /home/saldosys/public_html/wp-content/plugins/membership/membershipincludes/addons/login.widget.php on line 42"

I have read the forum with this link (https://premium.wpmudev.org/forums/topic/membership-login-widget-error-message) And i seems that i have the same problem.

I have tried to change the code like they wrote in the forum, and the same thing happened to me. When i have replaced the code, the widget doesn't appear at all.

So please can you help me get it to work!
