[osCommerce] Regenerating .htaccess file in multilanguage

[rikic]

Hi!
last week I've installed a new language on my new website.
everything was ok, but now (due to the changing of the urls) I've lost my positon in the organic of google....
I've tried to copy the old Rewriterules at the bottom of the new .htaccesss files, but when I recharge the website, MSU regenerates the file, delating all my changes...even if .htaccess file has 644 permissions (rw-r-r-).
someone can help me please!!!
I'm getting crazy!!
thank you very much!!

To protect your .htaccess file content, please set .htaccess file permissions to 666 and/or create "readonly-htaccess" file within same directory (note there is no dot at the beginning of name of this file).
