phpMyAdmin does not give any friendly error on syntax error in config file as it used to give. It happened to me after using short php tag with PHP 5.5.
In case there is fatal error in config file, execution is terminated and user is left with blank page without any hint what is wrong (because we disable error reporting for loading config file).
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

I don't think this is fixable while using PHP as language for config file...
Now implemented in git using shutdown function.
