Hi, my WordPress is down, I see this error in your plugin, can you please fix it:

Fatal error: Uncaught TypeError: call_user_func(): Argument #1 ($callback) must be a valid callback, class Kirki\Module\CSS does not have a method “get_instance” in /home/lidogr/public_html/wp-content/plugins/et-core-plugin/packages/kirki/core/class-kirki-modules.php:91 Stack trace: #0 /home/lidogr/public_html/wp-includes/class-wp-hook.php(341): Kirki_Modules->init() #1 /home/lidogr/public_html/wp-includes/class-wp-hook.php(365): WP_Hook->apply_filters() #2 /home/lidogr/public_html/wp-includes/plugin.php(522): WP_Hook->do_action() #3 /home/lidogr/public_html/wp-settings.php(720): do_action() #4 /home/lidogr/public_html/wp-config.php(89): require_once(‘…’) #5 /home/lidogr/public_html/wp-load.php(50): require_once(‘…’) #6 /home/lidogr/public_html/wp-admin/admin.php(35): require_once(‘…’) #7 /home/lidogr/public_html/wp-admin/index.php(10): require_once(‘…’) #8 {main} thrown in /home/lidogr/public_html/wp-content/plugins/et-core-plugin/packages/kirki/core/class-kirki-modules.php on line 91

Hi,

Thank you for reaching out to us.

The Kirki Customizer Framework plugin is currently activated on your website and it may conflict with our XStore Core plugin. To ensure seamless functionality and performance, we kindly recommend that you disable the Kirki plugin.

Please be informed that the XStore Core plugin already encompasses the Kirki framework within its own codebase. To avoid any potential issues, it is advisable to deactivate the Kirki plugin while utilizing XStore.

Warm Regards,
The 8Theme Team
