Redirections

Hello everybody:

I have problems trying to install plugins. When I go to ‘add new plugin’, appears page saying ‘Restablised conection’.
I have spoke with RAN.es and they says to me that is because redirections.

The problem appear last week when server changed Control panel page acces from ‘admin.ran.es’ to ‘sanjosehfi.es:2222’. But I have got not idea where search this in WP code files. I tried in ‘ftp_permisions’ file of ‘wp-options’ table without luck.

Can someone help me?
Thanks in advance!!!
