When I attempt to visit the phpmyadmin index page i.e. http://localhost/phpmyadmin/index.php I get: Cannot load mysql extension. Please check your PHP configuration. error message Now, I assume that 'mysql extension' and PHP MySQL package are actually the same thing, but different names. Using synaptic debian package manager I can see that I have php5-mysql installed so I should not be getting the above error message. I suspect that phpmyadmin has made an assumption about the path location of the PHP MySQL package so all I need to do is find how/where phpmyadmin looks for the PHP MySQL package. Can you advise me where the phpmyadmin settings are stored?
