I am beginner in Magento, but I designed a Magento v. 2.3.5 locally under xampp and everything is ok
I transferred it to the server and applied all the modifications in the env.php file and in the core_config_data table.
When I launch the URL of the site in the browser, the Design CMS of the site disappeared (see photos Local and server) and impossible to access the administration (error 500).
Anyone for a solution? Thank you !
