I want to install chamilo in 1and1 when I transfer all the files that I downloaded via FTP to the official site so after I have linked to the subdomain it works an error:
Fatal error: require (): Failed opening required /homepages/...../ chamilo / vendor / composer /../ symfony / polyfill-mbstring / bootstrap.php '(include_path ='.: / Usr / lib / php5.6 ') in
Chamilo / vendor / composer / autoload_real.php on line 66
I tried to proceed differently by sending it from ssh but the server of 1and1 does not recognize the command sudo
If anyone can help me find the solution
