I have a problem in Sitefinity 3.7 SP4 with custom CategoriesView which was described in article(http://www.sitefinity.com/blogs/ivandimitrov/ivanposts/10-02-15/optimize_backend_categoriesview_performance_in_sitefinity_3_7.aspx). When I am trying to activate this custom template on Sitefinity 3.7 SP4 It makes strange issue: I can't see link "Categories" to view categories for my module.
Why can It happen? Maybe you change naming for Telerik.Libraries.WebControls.Admin.LibrariesControlPanel?
Why this fix didn't include in SP4? I asked this question from SP2 release. =)
