Reply To: Impresively slow and sometimes even not loading.

Hello,

Seems that your server is not stable because on the default theme, we can see that site loads around 4s and It’s not normal for the default theme. On the default theme, the page should load around 1s.

So you need to check what is wrong with the server because it loads slowly on the backend too so it is not something caused by the theme.

Kind Regards
