When I began to import the product, it was taking a looooong time so i stopped the script through the browser (or, at least, i thought that i was stopping it).
The POST table stopped working (didn?t accept new posts, perhaps it was locked??) and server load INCREASED A LOT, it was TERRIBLY HIGH. I closed the forums.
The POST table was repaired through SSH several hours after the disaster.
Incredibly, when the forum was again up and running, i realized that the installation of the hack had been succesful!
It is working now. I have just upgraded to 3.8.3 from 3.8.2 and it is running fine.
