Make CHILD themes. http://codex.ww.wp.xz.cn/Child_Themes
You have to edit the CSS file to explain to WordPress what the new name is.
You don;t need to make multilingual version of each *theme*. they are localized already, you just need language packs for the themes or WordPress itself.
then you can make a new site to do the actual content for each language.
Firstly thanks to both of you! I tried a few things but didn’t manage to do what I needed to :(.
@ Ipstenu: is it really needed to make a child theme in this case?
@ Andrea: could you please be more specific? I guess I didn’t understand what you mean.
Thanks in advance
If you have a need to make a ‘duplicate’ theme, that is only different in small ways, it’s better (and easier) to make child themes. http://codex.ww.wp.xz.cn/Child_Themes
But. What Andrea means is that you can download the language packs (from http://codex.ww.wp.xz.cn/WordPress_in_Your_Language ) and apply them per site. Saves time and money 🙂
I guess it works now, thanks :)!
Here I am once again :(. I tried a couple of things without any success. I wanted to place some flags on the right site of the header of my twentyten theme to allow any visitor to select a language just clicking on the flag. Firstly I tried working on the header.php and placed some code there and then in the style.css to add some specifications. Beside having a different result on each page (strangely it looked different in the en page than in the es one etc….), it just didn’t come out like I thoght. Any suggestion to help me? I remember i had seen a twentyten theme with the flags in the posision I wanted them to be (just underneath the navigation bar under the header image) but I can’t find it anymore. Thanks again………..
Likely those flags were added by a plugin.
