I've made a swedish translation of the sugarCRM language files for vers. 6.5.7.
I haven't found a en_us.lan-pack so I tried to modify the en_us language-files found on the server.
Then I downloaded a russian language-package to see what files/directories needed and then I packed my translated files the same way.
I use the module loader and the lang.package is uploaded just fine. I then moved to "langages" in the admin section and enabled swedish.
I then signed out, closed the webbrowser and went back to our sugarcrm and now there's an language option added. See attached picture.
However, when i choose "Svenska", the page goes completly blank. If I try to view the source code, it's also completly blank.
So my choice of swedish is unusable. BUT WHY? And how do I correct it?
