help. Upgrade and change language fails

Hello friends. I need help. I installed the 2.0.1 as my SMF forum. the installation do it from my server, the installation path is user / public_html / forum

This shows the installation with automatic installer nixiweb. By default installed version of smf

everything was fine. but the old version that is installed and enter the package manager to update kicks me a blank page. if I go to change language, also brings me to a blank page. that could be happening?

Eejemplo: click language / add language / spanish selected.

It happens that brings me to a blank page.
