vBET2.4.3 displays blank page

[POL_ED]

As a new online hello all.

I received information that I can describe the problem in jęz. Polish.

VBET2.4.3 installed free from vbulletin.org / forum / showthread.php? T = 232456 & page = 25
on vB 4.1.0 PL2.
Unfortunately, when you select any language (flag icon) displays a blank page.
mandrivalinux.eu

I conducted a test and turned off all mods installed and the situation has not changed. Still when you select any language displays a blank page.

For a test I installed a copy of vB4.1.0 PL2 forum on another server and everything works fine.
mageiaforum.eu

Htaccess file on both servers are identical.

I do not know where to look for the error.
How to fix it that the translation of vBET work?
