For some reason, your website is experiencing troubles loading it’s PHP files so as such it’s throwing an HTTP 500 Server Error. These errors won’t show in your Web Server’s error log. You’ll need to check that log.
If you don’t have error logging enabled in your PHP, here is how you can do it
Enter your website’s directory. The directory will be specified in your website’s Apache Conf. Usually the directory is
Once you are in the folder, open your php.ini there. If you don’t have one, you’ll need to create it.
Once you do, input the following in it
; log PHP errors to a file
log_errors = on
error_reporting = 32767
error_log = /path/to/file
Notice, there is an errorlog line. This is where you’ll need to create an errorlog for your website. Create the file exactly how you named it in your php.ini, in the same folder.
Once you’ve done it, restart Apache and you are ready to go. Next time you open your website, you’ll see the exact error in your php error_log.
