Any update on this?

Hi,

Please ignore this.
$valid_for = $swpmmembershiplvls->column_default($request, ‘valid_for’);

$swpmmembershiplvls = new SwpmMembershipLevels();

This above code is causing this issue. Simply i’m trying to create a object using “SimpleMembershipLevels->__construct” function which internally calls WP_List_Table->__construct function where this issue is occurred.

$swpmmembershiplvls = new SwpmMembershipLevels();
$valid_for = $swpmmembershiplvls->column_default($request, ‘valid_for’);

I have used this in my code. And it throws the above error. Because the function convert_to_screen() is not accessible from class.swpm-membership-levels.php

require_once( ABSPATH . ‘wp-admin/includes/template.php’ );

Import this in the class.swpm-membership-levels.php. Will solve this issue i hope. Please check and update the build.

Thank you,
Bala
