Hi when I go to mw-config on my website it shows the blue boxes they should be hidden which they were which indicates a js problem. Please fix it.
I am running mediawiki 1.26 wmf22
To reproduce download Mediawiki from either the master branch or wmf/1.26wmf22 branch install mediawiki on your website then go to mw-config on your website it should show the blue boxes by default. They should be hidden like they were before.
