Hi all,

After Activate "WPBakery Page Builder"  Version 5.4.5, when I click "edit" in pages cards, on screen appears error and I can't use Visual Composer or edit any page. 

Fatal error: Uncaught Error: Call to undefined function filter_var() in /public_html/wp-content/plugins/js_composer/include/classes/shortcodes/shortcodes.php:310 Stack trace: #0 /public_html/wp-content/plugins/js_composer/include/classes/shortcodes/shortcodes.php(1498): WPBakeryShortCode->printIconStyles() #1 /public_html/wp-includes/class-wp-hook.php(298): Vc_Shortcodes_Manager->buildShortcodesAssets('') #2 /public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters('', Array) #3 /public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #4 /public_html/wp-admin/admin-header.php(118): do_action('admin_print_scr...') #5 /public_html/wp-admin/edit-form-advanced.php(472): require_once('/public_html/wp...') #6 /public_html/wp-admin/post.php(173): include('/public_html/wp...') #7 {main} thrown in /public_html/wp-content/plugins/js_composer/include/classes/shortcodes/shortcodes.php on line 310

Hello,
please first try to disable all plugins except VC and check again.
Make sure that the theme and plugins are all up to date as well.
thanks
