Fixed secondary menu links in small view in IE8

The issue is caused by the fact that IE8 HTML view doesn't use quotes around class. The search and replace created the followin markup `<A class= href="/v4.0-ci/index-en">Item 1</A>` which was interpretted as `<A class='href="/v4.0-ci/index-en"'>Item 1</A>`
