500 Internal Server Error

Trying to Install something onto my Domain.

I keep getting a 500 Internal Server Error, it is due to php_value, but when i remove it the subdomain acts as if its using my main.

Error Log:

b**** [Sun Mar 04 19:50:49 2018] [alert] [client ******************] /home/sites/3b/7/704b7473e4/public_html/****/.htaccess: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

The error log will usually display the line number of the broken code. Most php errors i have found are usually missing closing brackets { } or () and/or semicolons ;
