When going to a website, Apache can report an Internal Server Error 500, which indicates there is a problem with the content. Reviewing the Apache Error_log can help identify where the problem is occurring.
If the php_value is an issue, then you will see a line similar to the following:
[Tue Apr 27 00:15:10.724221 2021] [core:alert] [pid 88611:tid 47191295141632] [client 192.168.1.10:45406] /home/cpuser/public_html/.htaccess: php_value not allowed here, referer: http://www-domain.tld
To correct this error that is being reported in the Apache Error_log, the php_value lines would need to be removed from the reported .htaccess file like the following example:
php_value max_execution_time 120
