Hi Guys I get the following error trying to installing a wordpress theme manually ERROR 500 - Internal Server Error! The following error occurred: The requested URL caused an internal server error. It is the following set-up: The Perfect Server - Ubuntu 18.04 (Nginx, MySQL, PHP, Postfix, BIND, Dovecot, Pure-FTPD and ISPConfig 3.1) I cannot see any error in the nginx, pure-ftp, php7.2-fpm. sr site error logs. Please help
There should be an error in the error.log file of that website or in the access.log (/var/www/domain.tld/log/ folder) for a 500 error. The most likely reasons are a php code error in that theme, the theme is not compatible with php 7.2 or you did not chown the files to the user and group of that website.
