Tawk not showing in post pages only main pages

Hi!

I am trying to have the tawk button show up not only in my main pages, but also in my post pages. However, it’s not happening… here’s what I’ve tried so far:

• cleared my cache (what feels like 100 times)
• tried 3 different browsers (cleared cache again)
• disabled all plugins (it doesn’t matter which plugin I disable it consistently refuses to show up in post pages)
• tried a different theme – no success

I don’t know what else to do ?? Can you help?

The page I need help with: [log in to see the link]
