PHP文件中的500 Internal Server Error

Question

I have a problem. I installed CentOS Web Panel and varnish cache on my VPS server. I have two domains, two hosts on a VPS. One website is using WordPress other is not. Now everything on non-wordpress site is working (html,js,css,picture files...) fine except that PHP files are not working now(Same on WordPress). Just one file is working named testmail.php , which contains: <?php echo phpinfo(); ?> <?php echo phpinfo(); ?> Here is apache error log:

I've noticed that i have two php.ini files one is at /etc/php.ini other is at /usr/local/php/php.ini (used by server) and I also have two httpd.conf files one is at /etc/httpd/conf/httpd.conf other is at /usr/local/apache/conf/httpd.conf (used by server). I've also noticed that there are no modules( mod_rewrite.so .. or any other) in second apache config file(used by server).

I tried to change ownership (chown) and tried to change file permissions (chmod) but nothing works. Can you help please?

500 Internal Server Error occurs from following reason. you can solve by followng:- 1.If you have not given file permsission you can get this error. Please give file permission.

2. Or Open Apache's httpd.conf file you have to find following lines, and remove #

   LoadModule rewrite_module modules/mod_rewrite.so

LoadModule headers_module modules/mod_headers.so

3. you can also check your htaccess is file or folder is allowed or not.
