Please select one or more themes to update. (Error to update NewsPaper Theme)

[bestery]

Hi, I have installed with my license the NewsPaper theme in AltervistaBlog:


However I can't update it from the theme dashboard, as I get the following error:


As expected, it does not throw me any theme update from the native wordpress dashboard.

How can I fix it?

Did you unlock the server to server connections? (from Settings)

It should be "External access without restrictions".

Bye!
