Normally I use PHP 7.2 for Magento 2. Recently I received a complete project in Magento that is not running in PHP 7.2, so I change my PHP version to 7.0 also. Install all required extensions in PHP 7.0 version
and when open my project Home page receiving this error. after that also run all issue related commands like:-
sudo apt-get install php7.0-dom
and
sudo apt-get install php7.0-xml
but my problem is not solved.
Please help
