SOLVED! After proxypass suphp problem

You did a proxypass to run your web site from a new server, all is working well but you are taking internal server error (500)

listened logs in new server by the command

tail -f /usr/local/apache/logs/error_log

[Wed Aug 04 17:46:39.834771 2021] [:error] [pid 76219:tid 140220137727744] [client 192.168.x.x:48738] No user or group set — set suPHP_UserGroup, referer: https://newhost.ip.address.or.domain

just you need to edit

/usr/local/apache/conf.d/suphp.conf

change directory with your host directory and change usergroup with the domain username

<Directory /home/mydomainuser/public_html/>
suPHP_UserGroup mydomainuser mydomainuser
</Directory>

good luck!
