I have set up an Apache server on a Zorin distro and I have HTML and php working in the browser and MySQL working from the command line. When I install phpmyadmin, it appears to run but only displays a blank screen. I have turned on error reporting in the php.ini files mentioned in phpinfo() but no errors are reported. To test the error reporting I created a PHP script containing a deliberate error and that error isn't reported either. Are there other directives I should be setting to enable error reporting to both console and a file? Can anyone suggest what may be wrong or steps I can take to discover the reason for my issues?
