Subject: RE: [users@httpd] Unstable PHP under Apache
archived-at: Tue, 02 May 2017 15:24:21 -0000

With your current configuration, PHP is not operating.  If PHP was operating
you would (or should) have an entry in a PHP.log. 

My suggestion is to eliminate your current PHP installation and use the
default installation available with your operating system.

After PHP is operating, perform the modifications you desire.

Somewhere, in this chain you mentioned you did not use the method of
installing PHP that was available with your operating system, because it
would update PHP without allowing you control.

Rather than modifying the standard installation of PHP, modify the actions
of the program that updates your operating system.

That's the weird thing - there nothing in the php.log and php-fpm.log has
only errors originating from the batch file processing.  (these are 
legitimate).   

In the Apache error log, nothing.

In the Apache access log, the response is shown as 404 even though the
browser displays "No Input file specified".  If I deliberately change the
request location to be wrong, then the browser displays the expected 404 and
so does the Apache access log.  The Apache error log never writes anything
for this.
