On any version of phpmyadmin 4.1.x includign latest 4.1.4 I get popup long red boxes at the bottom saying undefined, they have a button as well that says undefined. It pops up on various pages such as the status page. version 4.0.x and 3.x do not have the problem. Software as follows.
Windows 7 Pro SP1
PHP 5.4.23 FPM
phpMyAdmin 4.1.4 (affects all 4.1.x)
Mysql percona 126.96.36.199.0
Using mysqli phpmyadmin side and mysqlnd on php.
Directadmin is installed, phpmyadmin is accessed via a weird proxypassmatch configuration configured by the directadmin custombuild script, this possibly is related to it as I am guessing this is not a widespread bug given its still happening in 4.1.4.
