Hi,
I upgraded MediaWiki from 1.24.6 to 1.26.3. And now I am having problem with double quotes in page name. I can't create page with this characters in name. And I can't also find page with this symbols in name. My browser (Chrome 50) return error ERR_TOO_MANY_REDIRECTS. I have other MediaWiki version 1.24.6 on this server. Works without problems.
MediaWiki 1.26.3; PHP 5.5.35; MySQL 5.6.30; Apache 2.4.20.
Thanks.
