language issue in portal

Hello all,

One of our ESO portal system was installed and currently its working fine. But the main issue here we face is that when we click the portal link all the language information comes out in English though we requires the Spanish language.

Could anyone kindly give me some hint that whether we are able to change the current language to Spanish or we have to install the portal from scratch. Appreciate your kind help.

Let me know if I put these message in wrong forum as its a Basis issue.

Regards,

Jituda
