In 1.8.3rc1 frontend have many problems in Ukrainian and French languages of web-interfece
The reason I think that in these two languages are very often used an escaped apostrophe in strings translation \'
Probably some of the lines causing the problem.
- top menu not clicked by mouse
- cancel button not work in all places
- and other....
I determined that this problem has started still from branches/dev/dev-465 revision 13330
Additionally: with English locale open in IE8 items.php and you see some error on page is present - icon in window status. And after try to open or create Item - is impossible.
Tested on two different zabbix installation, from two different workstation in several browsers.
