We have updated all the translated PO files. However, there is an odd issue coming. 

We have reviewed the whole site. 90% content are translating. On some pages some sentences are not translating. Our team has reviewed all the codes and files once again. They are all working properly.

We have noticed the issue. Somehow from some PO files some text are not translating but rest of the text are translating from the same file. If there was any technical problem or our coding was wrong then none of them would get translated.

Here is an example, after login if you go to the profile page , then you will find Japanese text. But in the main page the RSS tool-tip text are in English. Both of them are coming from same file. If there is any error in coding or the file is corrupted then none of them should be shown on the front end.
