Technical keys are visble despite being translated

I have unpacked tar.gz file with translation but when I enter Wizard for setting up the journal I see also the following as in image in attach.
I see keys although translations are present there on cyrillic.
please advise.

Hi @vvucic,

I’m guessing you’re working on OJS 3.0?

I’d suggest validating the XML files – it’s possible that there is a typo early in the file that’s causing OJS to fail parsing anything past the typo. I use xmllint to do this, e.g.:

xmllint --noout path/to/file.xml

Yes, I am working on OJS 3.0. I guess, I have to validate all xml files. Locale.dtd is referenced. Should I use it from en_US?

Thanks

Hi @vvucic,

Have you made any changes to the locale files, or are these the stock ones from OJS 3.0?

Actually, I found some differences in some xml files done by other translator. I have sent him mail and asked for information about changes since one xml file has more than 200 lines less than original in en_US. I will keep you posted.
