problem installing theme

[ssbismark]

hi there,
i am new in prestashop and probably i still don't know much about how it works,
i downloaded free prestashop theme black diamond,saved it on my folder,extracted it and uploaded
using filezilla to themes files on my saver,when i open my bo preferences>appearance>themes,the new
uploaded theme doesn't appear,only the default prestashop theme,is there something else need to be done
apart from what i have done so as to successfully install a theme?
i am using ps 1.2.5.0

thanks a lot!

See the structure of defaut PS theme to know how to upload exactly your theme folder.
Your theme folder must be in the same dir as defautl ps theme!

thanks a lot vietGuide,
i have succeeded to install them successfully,
but the only one problem i have encountered is that after installing,i have tested these two free ps themes,black diamond and orange-boutique,all of these on my front page,some features and blocks are missing when i use them,category items are missing and some texts of some links are missing,don't knw really what's wrong or whether they're not compatible with with ps v.1.2.5.0,

any idea please?

If the themes were made for Pretashop V1.1 and you have V1.2.5 you can go to Preferences in the Back Office and at the bottom of the page you can select v1.1 theme compatibility.
