Every tab in Admin Dashboard that is under "admin/system_config" url give me this error:
Notice: DOMDocument::loadXML(): xmlParsePITarget: invalid name prefix 'xml' in Entity, line: 1 in /var/www/vhosts/chite-lingerie.it/httpdocs/vendor/magento/module-config/Model/Config/Structure/Reader.php on line 134
Also i cannot use cli command "config:", every time i try i give the error above
All other command or admin tab works good
Someone can help me?
