How to view error that occurred in page template?

This error occured when I tried to change the language from English to Nepali. I am using the same code for this as I used for other languages, only making changes to placeholder. Other seems to work fine but I am facing problem in this one.

Please what?

You need to indent your 'code' by four spaces (or we can not see it)
