Is anyone else experiencing problems when trying to add new blog posts? I've been using squarespace for a long time and 7.1 since release, Just tried to add a new blog and I no longer get the pop out window to edit tags, seo, images etc? It just loads a blog page and I cannot for the life of me access any of these options?

I'm using the blackbird layout and when you load my website the mobile menu is missing? Please help!
