I have a problem with saving my account user options when the extension Lingo is enable. I have updated my Mediawiki on 1.27.1. Additionally i have updated all used extension's also Lingo.
So i will edit my account user option and click to save all Parameters go back to the default value. If Lingo disable in the LocalSettings.php i can save every changes i've made. I've also tested Lingo 2.0.0 but it's the same effect.
I've tested the old Version 1.2.0 of Lingo and the user option works properly.
All other function's like browse pages, edit pages, view special pages and so on are okay.
