Forum .LRN Q&A: Re: Re: lors errors and questions ...

missing message keys can be fixed by yourself even if you are not very familiar with openacs. The error means that there is some text on the page that has not yet been translated to your locale. So this is not a "critical application error" more a warning.
Just go to /acs-admin/apm/ where you have a list of installed packages. Click on "Lors Management" and then on Internationalization. Under "Localize messages in this package" you can now translate your missing message keys.
