Sometimes translation is wrongly applied to html code of .tt files. For instance, <p class="title"> becomes <p class="titolo"> (in Italian). This causes a silent error, with nothing in the Javascript console... Stefano

We have translated koha into Armenian and installed it on our system. However, when we are switching from English to Armenian, in the staff section strange layouts are used instead o the default ones.

My first guess would be something in the translation is causing a Javascript error, I've seen this happen before.

Go to that page with the Javascript error console open in your browser and see if you see any critical errors appearing that don't when you do it in English.

If you see something, it might help you look through the translated file and see where it's coming from.
