Hello, i edited the wp-config.php file via FileZilla but i dont get any debug.log. It simple to create the same error. You just need a WPForms Lite with a simple form and protect that page with your plugin. After you enter the password to enter that page and fill the form and after clicking Sumbit button, the next thing that happens is a blank page with error “0” on it. It only happens on the pages which are password protected.
