Translation of "Search" and "Read more" in multisite installation?

Hello,
I saw your thread how I can translate "Search" and "Read more" in the searchform.php and front-page.php. My issue is that I have a multisite installation of the Black Bird Pro theme in three languages - each site for one language. If I make code changes in the theme, this results at all multisite pages. How can I resolve this?
Thank you!

 

Hello,
This is not possible to do with our theme.
You can translate those text manually only in one language.

 

Hello,
I replaced the search form with the language flags from "MultiLanguage Switcher Plugin" in the header.php:
(I replaced at lines 119-121:
<div class="top-search">
<?php get_search_form(); ?>
</div>
with:
<?php if (function_exists("the_msls")) the_msls(); ?>
Can you say me how I can center the flags in the height of the menu bar and put those at the right side.
Please see the image bellow. Hier is the link to the site: http://www.limousine-klagenfurt.com/wordpress/en/
Thank you!

 

Hello,

Add flag code inside any class
like:
<div class="flag"><?php if (function_exists("the_msls")) the_msls(); ?></div>


After that Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

.flag {
float: right;
margin-right: 10px;
margin-top: 16px;}

 

Thank you, perfect!
