Hi everyone!
Recently i’ve faced strange bug with toolbar. Instead of a normal names it shows codes (?):
Couldn’t find anything similar to my problem. Any ideas on how to fix it?
Hello!
Those codes are translation keys. They are the names of the texts your UI should access to provide content in your language.
Seeing them instead of any value means that somehow the place where XWiki wants to use those can’t retrieve any value for these keys.
I’m not sure what the issue is beyond that. You might have overwritten and’or deleted those translations. On the fresh 16.1.0-Snapshot distribution, in english, I can’t reproduce your issue.
You might want to check how to contribute translations at Languages @ Weblate XWiki.org. However from what I remember your XWiki should fall back on the english alternative if your language does not have a translation for these texts.

These should be in the page CKEditor.Translations (``). If you deleted this page, that might be why the translations values couldn’t be found.
Hey! Thank for quick respond! I think this bug poped up after previous update. Maybe it deleted some pages… Do you think if I updgrade to the latest version it will fix the problem?
I’m not the most knowledgeable on this, but I doubt an upgrade would fix this problem unfortunately (even though I’d still advocate to upgrade 
to be up to date with all the improvements and latest features). You can probably try repairing the CKEditor Integration Extension if you don’t have anything custom based on the changes
