I followed all instruction mentioned in topics about problems with dropdown edit. There was instruction in which many people mentioned, that I need to disable all languages exept english. In Locale section in admin panel i saw three languages (ENG, ES, RU).
ES is invisible language in Languages section. In Firebug I see two languages selected as Disabled (RU and Es), but i cannot see ES on list.
This is not critical, but it took me some time, to find out, where is the third language
I’am using latest version og SuiteCRM downloaded from official site.
