watermark

Hello
We have a web-based wordpress and has been the reference to the watermark in a directory outside the main.

http://sitio1.com is where it is installed wordpress (User /home/sitio1)
http://sitio2.com is where is the watermark user /home/sitio2)

We changed in the tables in the second bbdd site by the first in all those records where we have found and ….
!! stops working page!!
We are new to wordpress and the application was already done when we have picked us. We can not make many changes because it is in production for some time and the gallery is quite big

We have conducted searches (with the command grep) but we did not find any reference to the second site in the archives where you installed the gallery.

Any idea that helps us to “shift” this wrong?
