It is best to look at your log files and possibly include an error report. Put a simple script in your website that is just an echo line, for example:
<?php echo "Hello World!";
with the foregoing, there is very little that can go wrong. Work from there. Take a look at your phpinfo and see where your log files are located. Search
error_log
for the path to your PHP error log file and maybe look
display_errors
switched on.
This is something that has many features that can be the cause of your problem.
