Is there any reason OSticket can't exist alongside another PhP application?
None at all.Wiki doesn't say anything at all about a PhP configuration - other than PhP needs to be installed.
Any help at all appreciated

It might help to post the output of phpinfo.php (if it's on your system). Other than that, the 500.19 error generally signals a server misconfiguration. I'd Google that and see if anything helps. Are you trying to run multiple virtual hosts? There may be a conflict in the host config files.Jack
