conflict with WP Rocket

Ever since 2.4, I’ve been unable to use Move Login due to a fatal error. I tried to reactivate after seeing the update to 2.4.1, however, I still get this error:

Fatal error: Uncaught Error: Using $this when not in object context in /home/kindredgrace/public_html/wp-content/plugins/sf-move-login/inc/classes/class-sfml-options.php:171 Stack trace: #0 /home/kindredgrace/public_html/wp-content/plugins/wp-rocket/inc/functions/plugins.php(255): SFML_Options::get_slugs() #1 /home/kindredgrace/public_html/wp-content/plugins/wp-rocket/inc/functions/options.php(171): get_rocket_logins_exclude_pages() #2 /home/kindredgrace/public_html/wp-content/plugins/wp-rocket/inc/functions/files.php(126): get_rocket_cache_reject_uri() #3 /home/kindredgrace/public_html/wp-content/plugins/wp-rocket/inc/functions/files.php(204): get_rocket_config_file() #4 /home/kindredgrace/public_html/wp-includes/class-wp-hook.php(298): rocket_generate_config_file(”) #5 /home/kindredgrace/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #6 /home/kindredgrace/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #7 /home/kindredgrace/public_html/wp-admin/plugins.php(166): d in /home/kindredgrace/public_html/wp-content/plugins/sf-move-login/inc/classes/class-sfml-options.php on line 171

Looking forward to being able to use both plugins again!

Thank you.
