Ok... you mean that when you import the style file i gave you,
your forums appear in spanish? Please confirm that.

Please also tell me which options do you select when uploading the style.

Thanks a lot.

In the admin cp under Styles click Download/upload

in the new windows under Upload existing style set: (from your computer) Browse and select the style file you wish to upload. Set Overwrite existing style to the Default style. set Use style file even if it is for a different version of vBulletin to Yes, and hit the upload button.

And heres a screenshot of your style working on my forum under 2.2.8

BTW you will need to replace the vBulletin copyright in your footer template once everything is up and running, at minimum it sould read

Thank you so so so much for your help.
I'll update the (c) as well.

If you want to have vbportal and your templates then install vbportal and upload it's template as a new one (not overwriting default template) and copy and paste all the changes that are in vbportal templates to your translated one.
It may sound hard but... it's really easy.... 10mins of work + translation.
