Hello, I can not add widgets on the index page with the customization button. I removed all the widget because I had a problem with the slideshow (which was not displayed) and now I can no longer modify anything by pressing the edit button. The control panel works by the administration but not the Index page. When I'm on the index page, no link in the menu works too. Now have an empty index page and I can no longer have widgets for some pages in lateral columns. Does anyone know the solution?
