I have a large application that runs on a Ubuntu server and uses
prototype 1.7 and scriptaculous.js 1.9.0.

I just updated The OS from ubuntu 16.04 LTS to ubuntu 18.04 LTS.
The login page loads fine, but when the main page loads it
displays the php script that is loaded via AJAX as text, ie it is
not interpreted.
Then. after about 1 second, the page exits and goes back to the
login page.

A login failure redirects to the login page without displaying
any of the main page. So this is not a login failure.

Everything was fine under ubuntu 16.04 LTS.

Any thought as to what might be happening and/or any thoughts on
debugging it.

Here is the Apache2 error log:
...

Can you try adding a debug page in your web root? Something like <?php phpinfo(); ?>. Name that debug.php and visit it in a browser. See if it loads as php, and if it does, see if it runs as php. It sounds to me as though your apache server is not currently configured to use mod_php and interpret the code.

Thank you. The login page is php and the main page is php and
both load and are interpreted. The pages loaded through AJAX are
the ones not being interpreted.

If you enter the URL of the php script directly into the browser address bar does the server parse it as php?
Can you share the javascript that is making the ajax request? 
In developer mode on your browser do you see any javascript errors?

I fired up the Firefox web console and found no errors (a few
warnings).

As I was looking at the main.php code I saw a missing semicolon
after a heredoc closing identifier and put it in.

The next time I invoked the login script all went well.

Thanks for the suggestions.

I have no idea why it started working would rather be puzzled
than banging my head against the wall.
