Hi,
A server returns error 500. Investigate a web server error log file. Talk to your sysadmin if it's your own server or contact the host's support service.

There seems to be a problem with this version. I just uploaded and installed the old version.
The following version is up and running.
EspoCRM-5.4.5

What PHP version on the webserver? The latest EspoCRM supports PHP v.7.2+ only. PHP 7.1 is not supported any more.
Note, MySQL 5.6 and MariaDB 10.0 is not supported as well.
