Category and Single error

Hi, I’m using the latest plugin version 4.5 but I’m getting this error:

the error appears when I click on: Category and Single


Just refresh and try again, I tested your account just now and it works perfectly for project number 1851

Thank you so much, now is working but how you can see i the template of category and single are different respect the template of home.

And I can’t change/customize nothing on it:

You can add any block around it like the images, sliders etc…, remove an element, change the order of the elements and so on
