web page shows error

Hello,

I am getting this error on the browser: [an error occurred while processing this directive]. See attached screenshot. The web server error log shows following error: 

[Wed Mar 16 16:21:07.179929 2016] [include:error] [pid 16232] [client 127.0.0.1:47093] AH01337: Could not parse expr "$debug = 1" in /usr/local/src/markup-validator/htdocs/header.html: Parse error near '$', referer: http://validator.pakphp.com/w3c-validator/check

The webserver is apache 2.4. It is running on Debian Jessie and has a private ip.

It seems some of the server side include statements given in header.html are not being processed correctly by the webserver. The statements containing variables are given errors. I got rid of the error by entering following line in header.html: <!--#config errmsg="" -->. I used this link for reference: http://httpd.apache.org/docs/current/howto/ssi.html

Thanks,
