[Plugin: Mingle Forum] Please help – plugin activation disabled website

[giddybd]

I was looking for an easy plugin forum, and this looked like a great solution.

So I downloaded the plugin through my dashboard without a hitch, then I went to activate it and got this error:

Fatal error: Call to undefined function get_user_meta() in /home/content/99/6043899/html/wp-content/plugins/mingle-forum/wpf.class.php on line 1878

Please help. I can’t access my dashboard or my website, all I get is this error.

What can I do to get the site up quickly again?

Thank you so much for any help you can provide.

delete the plugin folder and it will deactivate automatically.
