Can you please do the following

In your wp-config.php file find and replace these global variables as follows

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

if they're commented out, uncomment them (I mean remove // from the starting of the line) and if they're not there, put these lines there in that file.

then open run that WordPress installation, don't worry its going to work right away, but we'll have the debug log which will tell us what went wrong.

Now if you can make sense of the debug log its good. If not copy the debug.log file located at wp-content/debug.log and paste it here so that I can review whats going on.

Worst case scenario, PHP5.4 might have been compiled with --without-mysql , in which case you'll have to recompile PHP5.4
