[SOLVED] Problem with modules and multilanguage - Joomla! Forum - community, help and support

hi masters,
i building multi-language site, can see test @ http://dani.cargohive.com/index.php (in spanish)
when change catalan (the flag @ bottom), there few modules not appear correctly (you can see them in home page): couple of modules not appear @ all, twitter module not show tweets , gallery 4 columns turns gallery 3 columns.
i installed update template (s**t, found in web) in hope corrected , now, besides still looks same, has added links russian sites @ top , bottom of articles (see @ http://dani.cargohive.com/index.php/bio).
i twice desperate before
could enlighten me know 1st- why modules displayed differently when in different languages , 2nd- tell me can hack in code? tried find firebug i'm noob

thanks lot!

i have fixed "russian hack" uninstalling update , installing again basic template, clearing cache.
but still have problem of modules not working in catalan version. has fact spanish version points http://dani.cargohive.com/ , catalan version instead points http://dani.cargohive.com/ca/
does have relationship? how should have spanish version pointing http://dani.cargohive.com/es/?
thanks again!
