How to Translate "Add""Remove""Checkout" etc.. from website frontpage

Using the translation file is the correct way to do it, and if done correctly I’m confident that it will work.

Note:
1. The translation file for Italian should be stageshow-it_IT.mo

2. You have to define WP_LANG (as it-IT) in your wp-config.php to turn on Italian translations.

3. The stageshow-it_IT.mo file should be stored in the following folder: {StageShow-Plugins-Folder}/lang

As an alternative you can use images for the buttons, see customisation in the user help for details.

Thank you! Now your solution works great! Where is the table in database of stageshow plugin? I’ve duplicated stageshow_sales.php in another site but this one has corrupted the site, i wanna try to copy also the table in the database or delete it totally and start another installation. What do you Think?

There are a number of DB tables for StageShow (how many depends on which variant of StageShow you are using), with table names of the form ****_sshow_**** . So, for example, the Performances table is “wp_sshow_perfs” on a default WP installation. Custom installations may change the “wp_” prefix to something else. StageShow settings are stored separately in an entry in the “wp_options” table.
To copy the database tables you’ll need to use a tool that allows you to access the MySQL database (for example phpMyAdmin) or write you own script to do it.

Copying a StageShow configuration to another site is possible, but can be very complicated and will almost certainly produce errors. Far better to do a clean install of the plugin on the second site.
