White Screen

Hi,

I’m getting the following error on my site which I suspect is causing the white screen of death.

call_user_func_array() expects parameter 1 to be a valid callback, class ‘UR_Shortcodes’ not found in /home/sites/***/***/***/public_html/wp-includes/class-wp-hook.php on line 287

This is on line 287:

$value = call_user_func_array( $the_[‘function’], $args );

Googling ‘UR_Shortcodes’ brought m to this site: https://github.com/wpeverest/user-registration/blob/master/user-registration.php hence my deduction that it’s this plugin.

Can you advise please? It’s updated to version 1.9.2.1

Thank you
