Hello translators and ambassadors!
Many users have experienced problems due to scripts using depreciated elements. An help page has been created to help those users to find the broken scripts. https://www.mediawiki.org/wiki/Help:Locating_broken_scripts https://www.mediawiki.org/wiki/Help:Locating_broken_scripts
Direct translation for translators: https://www.mediawiki.org/w/index.php?title=Special:Translate&group=page... - 29 translations units to translate, made with short sentences and documented.
I advice you to try the process described on the page before translating if you are not familiar with the use of browsers inspectors and Javascript debugging modes.
Ambassadors, this page may help your communities. Please share it with people who experience problems. :)
Thanks, Benoît
