Getting a plugin conflict with “pandemic-core” and “ReduxFramework”

Getting a plugin conflict with “pandemic-core” and “ReduxFramework” and as such once I install “pandemic-core” the site, my wp-admin gives me the “white screen” error.

The Error log gives me the following:
PHP Fatal error: Uncaught Error: Call to a member function dirlist() on null in /var/www/html/wp-content/plugins/pandemic-core/extensions/wbc_importer/extension_wbc_importer.php:107\nStack trace:\n#0 /var/www/html/wp-content/plugins/pandemic-core/extensions/wbc_importer/extension_wbc_importer.php(149): ReduxFramework_extension_wbc_importer->demoFiles()\n#1 /var/www/html/wp-content/plugins/pandemic-core/extensions/wbc_importer/extension_wbc_importer.php(71): ReduxFramework_extension_wbc_importer->getImports()\n#2 /var/www/html/wp-content/themes/pandemic/inc/redux-framework/redux-framework.php(179): ReduxFramework_extension_wbc_importer->__construct(Object(ReduxFramework))\n#3 /var/www/html/wp-includes/class-wp-hook.php(292): redux_register_custom_extension_loader(Object(ReduxFramework))\n#4 /var/www/html/wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters('', Array)\n#5 /var/www/html/wp-includes/plugin.php(484): WP_Hook->do_action(Array)\n#6 /var/www/html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-ext in /var/www/html/wp-content/plugins/pandemic-core/extensions/wbc_importer/extension_wbc_importer.php on line 107
