User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Build Identifier: 1. I install bugzilla2.17.6 on Redhat8.0 and I set everything up. 2. I download Chinese language package from http://sourceforge.net/projects/bugzilla-cn/, and I copy it into var/www/html/bugzilla/template/. 3. I changed parameters of bugzilla: language and defaultlanguage as cn. Result: the system shows error message: Saving new parameters New value for languages is invalid: You need to specify a language tag. Please hit back and try again. What the “You need to specify a language tag.�means? What I can do fix this problem? Anybody knows, please let me know. Thank you so much. Reproducible: Always
