Hi
First, before making any changes, it is good idea to make backup.
To update mudule, you need not only to upload files, but also to update the module in the admin section as is explained in this FAQ:
https://xoops.org/modules/smartfaq/faq.php?faqid=206
Also for some modules, there are aditional steps, so as suggested in the same FAQ - check any readme or other text files that came with the modules.
Also you may try the "Local Support" option from "Community" menu for different languages ...
