To know how to host a website, I create a Symfony4 project by putting content and I hosted it via FTP software at a free host, the problem is that I am faced with an error that I do not really understand (below):
Backslashes are not supported on Linux systems. Correct the backslashes with slashes on the file htdocs/vendor/twig/twig/src/Loader/FilesystemLoader.php on line 106 with the File Manager on the Client Area.
