Unfortunately, no improvement, even though I pressed CTRL + F5. I still got the same error.
But when I am in the panel, as Administrator, and press “Show Post” then I can se the page and the other pages to. So may be there is something wrong with the Index page (the first page on the Home page)?
But I have not made any changes in that page
What do you think about that - could it be that reason why I got the error when I try to open the main page (index page)?
