The translation tool does not allow you to use it. During the last days you can input the languages you want to translate and input the article you want to translate, search it, and select it.
The problem is that once you hit the start translation button, does not take you to the translation screen (the 2 columns) it just reloads the page, making you search and select it again and every time you press the button the tool is reloaded.
This happens every time that you want to translate a new articles (an article that does not exist in the language of destination), which is the main use of this tool. But, if you select an article that already exists (not sure why would you want to do that) it actually works as usual.
Many people are waiting for this useful tool to be fixed.
Thanks in advance.
